InWin 915 Case Review





To succeed in the market of high-end cases, you must create a case that is feature rich and highly unique. Over the years, InWin has been a pioneer in this market space with cases like the: S-Frame, D-Frame, H-Tower and now we can add the InWin 915 to that list. The 915 does away with the generic box shape of most cases and replaces it with curved 3mm anodized aluminum panels. Enhancing the curved panels are tempered glass side panels with the back panel being stylistically silkscreened with the company’s name. In addition to its beautiful aesthetics, the InWin 915 also includes some unique features such as: motorized top ventilation, expandable PSU bay, and system failure indicator LEDs at the front. Coming in at an MSRP of $449.99, the InWin is definitely priced as a high-end case which is quite justified with its intensive list of features and stylish looks.

Packaging & Unboxing

The InWin 915 arrives in a 29” x 15” x 31” (aka huge) white box with 915 being very prominent on the front.

Looking on one side of the box there is some InWin branding at the top and a list of technical specifications of the case.

The back side of the box is similar to the front, but includes the notable features of the 915.

On the other side, it shows you the color of the packages case (with ours being silver) and icons of the case’s features on the bottom.

The top of the box contains an unboxing guide which is quite useful as the case weighs over 43 lbs.

Opening the box, the 915 was nicely enclosed in foam and also included an accessory bag that I will address later on.

After following the unboxing guide, you can see that the 915 is also wrapped in a black bag.

Once the bag is removed you get your first look at the InWin 915. Our first impression of the case (other then weighing a ton) was that we couldn’t believe how beautiful it was. From the finish of the aluminum to the curvy nature of the case, it’s not like anything on the market.

Taking a peek in the accessory bag it includes:

  • Motherboard standoffs with socket
  • Hex screws
  • SSD screws
  • Cable ties
  • Water-cooling system washers
  • Graphic card holder
  • Pin header
  • Wire mounts
  • User manual QR code

A Closer Look: Exterior

After spending a little time with the 915, you can see that its design was extremely thought out and a huge emphasis on quality materials. Both the front and back panels are made from 3mm anodized aluminum and the top includes a diamond cut bezel which is just stunning. Both the front and back panels are made from tempered glass with an aluminum bottom to help protect it from accidental drops.

To remove the tempered glass panel, InWin has included a tool-less mechanized at the top left of case.

At the bottom on the panel included is an InWin logo cutout in the aluminum housing.

On both the front and back panels are spring loaded thumb screws to open them.

The front of the case is a solid curved aluminum panel with a barely noticeable LED strip at the top. The panel itself has a beautiful silver anodized finish and branded InWin in dark gray writing.

After loosening the front panel screws, it can be opened as it hinged on the other side. Once open, there is a removable bracket which can be used to attach up to a 360mm radiator or 3 x 120mm fans. If you wish to install a radiator you have a clearance of 56mm (for 360mm) or 53mm (for 280mm).

The back looks much like the front of the case with the exception of the removal of the 4 thumb screws and the bottom panel InWin logo. One difference is the “InWin” silkscreen that is applied to the entire tempered glass panel.

Taking a closer look at the back panel InWin has added some flare with InWin being silkscreened in multiple sizes and directions. This doesn’t only look great it also has the added benefit to help hide your wires at the back of the case.

Going to the back of 915 you have some exhaust ventilation and cabling cutouts.

Inspecting one of the cutouts you can see that the panel is made from a solid piece of 3mm aluminum

Opening the back, you now have access to the I/O which also includes a vertical GPU mount. At the top of the case is a motor assembly that raises and lowers the heat vents.

The top of the case features a curved front IO and a tempered glass center which raises and lowers the heat vents. These vents automatic raise with the computer is powered on and then also lower once shut down.

The front contours the curve and the I/O consists of:

  • Multifunction button that can be used to manually raise and lower the vent as well as can control the front LEDs
  • Headphone and mic jacks
  • Power button
  • USB 3.0 ports
  • USB-C port
  • Reset button

You can totally remove the top vent if you wish to install any radiators/fans in the roof.

Just like the front of the case InWin also includes a removable bracket.

Putting the case on its side, you can access the 2 magnetic fields located on the bottom of the case. To remove these filters, you’re required to either set the case on its side or tilt it enough to give your hand enough room.

A Closer Look: Interior

Upon removing the side panel you can see that the attention to detail and quality of the exterior made its way to the inside of the case. The interior is matte black throughout and is made from 1.5mm steel which makes it extremely rigid. The 915 comes with a full-length PSU shroud and the motherboard tray has various cutouts to run your cables.

On top of the PSU shroud, there are ventilation cutouts which will help airflow if you wish to install fans on the 2 included brackets. If you don’t wish to install fans on these brackets they can only be used to attach up to 4 x SSD’s or 2.5” drives.

At the front of the interior you can mount up to a 280mm radiator, 2 x 120mm fans or 2 x 140mm fans. Keep this in mind if you install a 360mm radiator at the front; you can only put 2 fans in the interior.

Looking towards the back of the case it has room for a single 120mm exhaust fan and includes 8 PCI slots and a vertical GPU mount.

Flipping the case to the back you have room to install 4 x 2.5” drives to the back of the tray and also an additional 4 x 3.5/2.5” drive with the drawers at the lower left.

Each of the 2.5” drive brackets are attached using a thumb screw and has the InWin logo embossed on it.

The lower drive bay includes 4 drawers that can be used for a 3.5” or 2.5” drive. If you don’t require them all and wish to have a larger PSU area, 2 can be removed and the divider can be moved over.

Each drawer is tool-less and sports the InWin logo.

The PSU feels quite roomy even in the default configuration with 250mm clearance. If you did want some extra room to tuck in those cables by removing 2 drive cages, you can increase these to 320mm.

System Build

The hardware included in this build is:

  • ASRock Z370 Tachi Motherboard
  • Intel 8700K Processor
  • 4 x 4GB Team Group T-Force Delta RGB Ram
  • EVGA 1070 FTW GPU
  • Cooler Master ML360R RGB AIO
  • EVGA 750W P2 PSU

The build was fairly straight forward and pretty much went as planned. I decided to install the 360mm AIO in the top of the case and the removable radiator bracket really made installing the AIO a breeze. Since there is only 70mm of clearance you can’t do a push/pull configuration in the top chamber. Even if you were to try and install fans inside the case there isn’t enough room between the motherboard and mounting points. An added bonus is that all the thumb screws on the case are attached and spring loaded so I didn’t need to worry about losing them.  Overall, the case was a dream to build in, all those little design choices really made for an effortless build. My only negative would be that moving around the case can be a little awkward at times with its shape and weight.

The back of the case had plenty of tie down points to manage my cables and the cutouts were positioned nicely with my motherboard. I decided to forgo using the included cable clips as my PSU cables are rather thick and were easier to just zip tie to the case. If you had a custom sleeved set of cables, I believe these clips would work quite well. The SSD was easily installed using one of the 4 included 2.5” drive mounting brackets.

Because my PSU cables and RGB controller are on the bulky side I opted to extend the PSU bay to 320mm. This was a little bit of work as it required removing 2 screws from the top of the PSU shroud and the bottom of the case. Once the divider was moved I had plenty of room to work with.

I really did like the design of the cable channels at the back of the case. In my opinion, this really cleans up the look over traditional cases.

Since the back is completely covered, it seems InWin decided the I/O cover was not needed. The motherboard sits a little back from the cutout and the cutout itself is too small to install the I/O shield. This is not a negative, it is just something I haven’t seen before.

When booting up the PC the first time it was pretty awesome seeing those vents pop up. Also, when shutting down the PC, these vents also close automatically. If at any point you want to close or open the vents manually, you can do so by pressing the multifunction button. In my option this is by far the coolest feature of the 915 and really adds to its uniqueness.

To get a good view of the front LED, I turned off the lights. Currently it matches the rest of my build since it plugged into the same RGB controller. If I wish to use the InWin built in controller I can press and hold the multifunction button to switch modes.

Final Thoughts & Conclusion

When shopping for a high-end case you’re often looking for something that has excellent build quality, is highly customizable and that has wow factor, the InWin 915 has this in spades. The moment I took the box off the 915, my eyes were drawn to its curved aluminum body and sparkly silver finish. Once I start building in the case, it was apparent that every feature/design choice was well thought out and was executed flawlessly. Some of the standout features for me were the removable fan/radiator mounts, expandable PSU bay, full length PSU shroud and the motorized heat vents. The build quality and choice of materials are phenomenal, the 3mm exterior aluminum in combination of the 1.5mm steel in the interior make for a very rigid case. The only drawback to building in 915 would be its sheer weight, especially with a full build. But this can be forgiven as that’s the price you pay for quality construction. If you’re in the market for a top of the line case that really stands out from the crowd, the InWin 915 just might be for you.
