Posted by on Wednesday, April 20, 2011 - 2:24am

Sentey is a manufacturer who happens to offer a range of cases aimed at doing just as we mentioned, winning your choice through design and features. If that name isn't familiar to you however, don't feel bad as they were an unknown to us as well. While they've been in the case scene for awhile now, it was mostly outside North America and less focused on the type of computing enthusiast that me and you are. As of more recently is it that Sentey has decided to expand their horizons, and seem to have made a decent impression in the short time. We have a couple models to show you from them, but today's focus is on their GS-6400R Arvina model, which comes from their Extreme Division line of cases. It offers a bold look, plenty of features and is hoping to win you over by offering them all in one case. So lets find out what it comes packing and if it managed to win us over!

Introduction to the Sentey GS-6400R Arvina Extreme Division Computer Case

In the beginning, computers didn't have cases... they had whole rooms, sometimes even buildings. Fast forward a couple decades to the advent of the Personal Computer and things started to bare resemblance to the more recognizable systems, all thanks to the invention of the microprocessor. It wasn't until around the mid-90s when we started seeing cases that you could buy off the shelf and build your own system in. From there we were introduced to the tower design and it's many variants, which over the course of the years has spawned even more variants of many shapes and sizes. While the majority will fit almost all the components available to us DIY builders, that doesn't mean they all will fit the roll we intend for that system in question.

The Full-Tower chassis size may not be the biggest case a person could buy, it is definitely the biggest of the "desktop" models. Gamers generally find this the most suited for their configuration, thanks to the greater interior space offered for all the components, which also leads to better internal airflow for lower temperatures. Go to any online or brick and mortar computer store and you'll find a vast array of choices to pick between, from a multitude of different manufacturers. All of which are trying to win you as a customer by offering up models in different styles, colors and coming with a laundry list of features.

Sentey is a manufacturer who happens to offer a range of cases aimed at doing just that, winning your choice through design and features. If that name isn't familiar to you however, don't feel bad as they were an unknown to us as well. While they've been in the case scene for awhile now, it was mostly outside North America and less focused on the type of computing enthusiast that me and you are. As of more recently is it that Sentey has decided to expand their horizons, and seem to have made a decent impression in the short time. We have a couple models to show you from them, but today's focus is on their GS-6400R Arvina model, which comes from their Extreme Division line of cases. It offers a bold look, plenty of features and is hoping to win you over by offering them all in one case. So lets find out what it comes packing and if it managed to win us over!

Sentey's take on the GS-6400R Arvina

What makes a case better than another? Design? Performance? These are two Key concepts that are present in the Extreme Division for hours of gaming.

The Sentey Arvina PC Chassis comes in three colors: black, red, and blue. Features a state-of-the-art ventilation system for what Sentey considers extreme cooling performance. The Sentey Arvina comes with six cooling fans with three of them positioned to ensure proper air flow inwards, while the remaining three are to remove the hot air produced by different components of the system. All of the cooling fans come equipped with color LED lights and it gives the Arvina a clean, crisp and modern look thanks to the all black interior. The Sentey Arvina GS-6400 PC case is backed by a limited one year warranty, which is on par with the warranty that comes on other cases.

Closer look at the exterior

The GS-6400R Arvina is quite the tower when you first see it. This model Sentey sent us is painted in a brilliant glossy red and it really stands out. It's constructed from SECC steel, with stylish plastic covers on the top, front and even bottom of the case. This all makes for a nice sturdy construction but we have to warn you, there is a downside. Being a full-tower case and made of steel means the Arvina weighs in at an impression 27.5 pounds!

First and foremost we see Sentey decided to go with the popular mesh style on the Arvina. First however, at the top we have the multimedia card reader which supports:  CF/MD, XD, SD/MMC, TF & MS/M2 cards. Now we can move on down to the 5.25" bays, which there are five of, the top two being intended for optical drives as they are stealth covers. The bottom area covers the internal-mounted front 120mm fan, and all covered with a dust filter on the back.


The biggest downside though is that these are not exactly use-friendly covers to remove. To do so you have to pop the front bezel off completely, but then it is just two metal tabs that need bending to remove the cover. You'll also want to take this time to do the installing of any optical drives or other bay devices since that also can not be done with the front bezel on. 

Making out way to the top of the case and we are greeted with the power button, four on/off fan control buttons, a tinted slide-cover and a long mesh ventilation panel; on both sides as well. The hexagon power button is outlined in a transparent blue ring and the power logo made up of the same plastic, which when the system is powered on will glow from the LED connected to the motherboard. While unfortunate that the fan controller does not have a speed dial, there is at least an LED for each channel to indicate whether or not the fan connected is on. Sliding back the spring-assisted cover reveals the I/O ports which provides us with: SATA Power and Data, eSATA, four USB2 ports, headphone, microphone, reset button and HDD indicator LED. Worthy of mention is both SATA channels are independent so you could have an eSATA thumb drive connected and an HDD at the same time.

Here we have a look at the top from the side, showing off the vents which should provide adequate flow for the twin 120mm exhaust fans. The side panel features a nifty external cover which act as inlet ducts for the expansion slot fans, which we will show you on the next page. At the back edge we have the side panel's latch release button, but if you prefer to use side panel screws then the Arvina also comes with two thumb screws preinstalled.

The opposite side is just a standard flat panel, though does also uses the same latch/thumb screw feature as the side above. No vents or extruding pieces present.

Moving along to the back of the Arvina, we see is painted in a nice semi-gloss finish. Two rubber grommets cover the watercooling tubing holes, and below them sits the fourth 120mm fan that Sentey has included with the case. Needing no introduction is the rectangular port for the motherboard I/O panel and trim piece, with the seven expansion slots below it. The red tabs you see are part of the tool-less locking mechanism, but don't worry, they are operated from the inside. 


Finally at the bottom, we have the opening for the PSU. There are a total of eight screw locations, indicating for the choice to pick whether or not the PSU is mounted fan-side up or down. 


Closer look at the interior

As said on Monty Python: "And now for something completely different." Before we get to the main event we wanted to show you what is behind the front, and under the top panels. 

As you can see, there is quite a bit of room up there. While it may not have been intended as a location for a radiator, if a person wanted to run a dual configuration, or add a supplementary 120mm then there is quite a bit of room. Keep in mind the bottom panel (which the cables are routed through) is unscrewed and moved back a bit, but if one wanted they could use the top two 5.25" bays to house a reservoir, with plenty of room for hoses to fit through the hole.

With the side panel of the Arvina popped off we have a nice view of the inside. We can see Sentey went with a completely blacked out interior, something we appreciate seeing on cases. 

Something you likely noticed straight away was the dual fan bar that is in place over the expansion area. It comes with two more fans, though only 80mm in size. To open it you simply push next to the Sentey badge by the hard drive trays which releases the latch, allowing it to swing open. A rather unique way has been utilize to power the fans. Instead of having two wires left loose, which could innevtibely be bent back and forth enough (or pinched) and cause them to break, there are two contact pads instead. So when the fan bar is 'open' there is no contact made, which if the system was on then the fans are unpowered, closing it reestablishes contact. While unnecessary to do, I had bent the copper tabs out just a tad more to insure better electrical contact, for my own peace of mind.) 

Over on the storage side of the case we see the the 5.25" bays and hard drive racks. The top four 5.25" bays utilize a tool-less latch to secure any drives installed. To install a drive you first lift up on one of the latches to basically 'unlock' the bay. When you slide in a drive there two sping loaded tabs on the opposite side with raised 'nipples' that fit into the drive's screw holes, then on this side there are two pins which fit into the opposite screw holes when the latch is pushed back down. A novel design in theory, but a little clumsy in practice. It does hold in a drive rather well though and we had no problems with a drive sliding out when we moved the case around. 

For the hard drive rack you have the option to slide the whole cage out if you like, though it is not necessary to do if you don't want. Each trayis removed by sliding the red tab over, where by two springs provide enough pressure to kick it out for you to grab. The trays support both 3.5" drives and 2.5" drives, which is really nice. For 2.5" drives there are four marked holes that you put the screws through from the underside of the tray, which you can see in the middle image. On the bottom image we see how the 3.5" are retained from sliding around and is rather simple in design and operation, at least compared to the 5.25". Lay in your drive, and then each of those red 'flaps' has a pin which again sits into the screw holes on the drive. Nothing is clicked into place on these, instead the snug fit of the tray into the cage prevents the flaps from opening, thus holding the drive in place. 

Here we have the expansion slots and the other side to the red tabs we had mentioned earlier. These tool-less tabs are a welcomed change from the old screw method, but also are required as the fan bar blocks any access by screw driver. Releasing them is a one-handed, two-fingered affair. Pressing on the curved portion with you thumb releases the tab, and pulling towards you with your index finger rotates it open. To close you simply rotate it till it clicks into place, again utilizing the pin-and-hole approach. We found pushing from the outside with your other hand works well to lock the tab in. Something we like to see are vented expansion slots, which the Arvina uses. However, as you know, something we don't like to see are the slot covers that have to be broken out and are not reusable, also something the Arvina uses.

A bit of advice when locking the tabs is to make sure the pin does indeed go into the hole when the tab clicks in, to avoid what had happened to us a few times. Wiggling the right side portion is all it took.

Motherboard backplate access for swapping of CPU coolers without removing the whole system. A standard 12oz can for size reference, which as you can see is easily able to fit inside with room to spare.

Also note the four cable straps to keep them in place for cable routing. These are reusable as well, so if any rearranging or component upgrades take place you won't have to cut any zip ties.

Here are shots of the four included 120mm red LED fans, in addition to the fan bar's 2x80mm over the expansion slots. We have: two in the top for exhaust or a radiator, one rear for intake/exhaust and a final 120mm for intake in the front and to cool the hard drives.

PSU foam padded stand offs and liner around back opening, to prevent both scuffing but primarily to dampen any vibration. To the right of the PSU mount is a fan location for a fifth 120mm or (seemingly) 140mm fan. Then a bottom shot to show off the red cover with six foam feet. The center is recessed to allow proper airlfow for the PSU and/or addition fan. Between the case and bottom cover there is also a clear plastic dust grill present. 


Included hardware and accessories

A nice little bonus that Sentey has included with the Arvina is a little case that is tucked nicely away in the bottom of the case, as you may have noticed in the first photo on the previous page. This holds not only all the screws and studs you might need, but also comes with a small screwdriver and soft terry cloth. You might be wondering what a terry cloth is doing packaged with a computer case? Well it's actually a rather thoughtful inclusion if you consider it's glossy paint job, as they are fingerprint magnets! Finally is one plain expansion slot cover, since as we mentioned earlier the Arvina uses ye-olde twist out covers. It's a nice addition, but considering there are 7 ports and the whole back panel is painted black. At least three that were painted to match would have been a welcomed sight, but we'll just have to make sure to carefully pick which slots we remove the originals out of. The last thing, which is small additional item (no pin intended), is the piezo PC speaker. Most cases don't come with one anymore, and not all motherboards have it onboard, so to counter that Sentey was thoughtful enought to include one! 

Also included is a mini-CD, presumably with drivers for the RealTek RTS5151 multimedia card reader, and a SATA/Power extension cable.



Installing the system components is pretty straight forward, and is something we've shown you time and time again. Still, to give you an adequate case size reference it needs to be done, so for this we used a Gigabyte 890GPA-UD3H. Here it is all bolted in and the front+top panel cables connected.

PSU Installed and power cables routed out the bottom rectangular port.

Everything all buttoned up. Front I/O area's eSATA and internal SATA port cables, front panel LEDs and button wires, with finally the USB audio header plugs are all connected to the motherboard. Also all the cables have been routed behind the case and the back panel on, though admittedly it was a tight fit since the gauge wire the PSU manufacturer used was bigger than some. A nice feature that might not have been immediately evident is there was a routing hole in the motherboard panel for the CPU Aux 12V cable, which made an extra clear install on the cabling; barely visible in the top left. Apologies for no shot of a graphics card installed, but rest assure that since this case can handle the Extended ATX (EATX) server and workstation boards, there should be zero problems with graphics card room. The ATX spec is 9.6 inches wide for motherboards (as the one used) and 13 inches for EATX, which there is a further 1-1/2 to 2 inches to spare before you reach the frame rails of the drives. No problem for even the lengthy HD 5970 or 6990 cards.



The GS-6400R Arvina case is a good entrance for Sentey into the enthusiast market. It offers a lot of features both internal and external, with a nice paint job to top it off. The outside comes in a nice glossy finish, while the interior is fully painted solid black. They made sure to back the slick paint job with equally good looks. Its front may be simple in design but it flows very well, especially into the top of the case. A job well done on balancing just the right amount of mesh in the design, enough to stay functional for airflow, but not too much to be an eye sore.

Good looks are not all the Arvina has though. There are a number of features that are of real benefit to have, not just a novelty. For starters we have the front multimedia card reader, supporting quite likely all of the currently storage card formats. On the top with in easy reach are four fan power buttons to give you control over the right amount of noise and cooling ability. Then there are a whole load of I/O options under a tinted sliding cover, offering connections for USB, eSATA, standard drive SATA, and audio. Moving inside there are twin 80mm fans to cool the expansion cards and four 120mm fans scattered throughout the case, bringing the total to a whopping six fans the Arvina comes with.

That isn't to say there aren't a few quirks with the Arvina. A couple of the tool-less designs could use a bit more work, to make them less of a hindrance, as that was the original point to tool-less features. Having to remove the front bezel to install or remove drives seems a little old fashioned for such a modern looking case. Speaking of old fashioned, the expansion slot covers that you need to break out in order to insert a card are something we had hoped to find only in the cheapest of cases, not to mention they only provide a single replacement cover.

Thus bringing us to the price. The GS-6400/B/R models are offered in three colors: black, blue and red (respectfully). Similarly priced, either of these three will set you back at least $90, and between $110 and $140 after shipping (depending on outlet size due to weight). Based on everything that is included with the Arvina, that is a rather reasonable price, but we would like to see some of those things improved before being able to give it the "Recommended" rating.
