A Closer Look – Inside
The side window of the Cooler Master MasterBox Lite 5 is the entire panel, can it can be removed from the case with 4 thumbscrews through rubber grommets and is also padded by a few pieces of rubber around the edges. Inside is a small brown box that contains the black and white color trim pieces that can be swapped with the stock red ones.
The front panel comes off by simply pulling the bottom firmly, than popping it off. We also noticed here the front panel is transparent, not opaque, so we might have to use LED fans in a bit when we put a system in this case.
Inside the box inside the case is the white and black trim pieces to replace the stock red ones.
The upper trim piece near the front I/O panel is held in place with 2 small screws.
The lower trim is held in place with 4 screws.
The lower trim has a filter screen that you need to move to the new trim before reinstallation onto the panel.
The main chamber of the case follows a standard ATX layout. A permanent ‘basement’ or power supply shroud divides off part of the case for this purpose as well as keeping everything looking great.
The main chamber also comes with a single 2.5” drive tray that can be mounted in 2 locations along the motherboard tray near the front, or 2 locations on top of the basement cover if you have a larger cooler in the front that might block the view of your favorite SSD.
Two thumb screws let you remove the right-side case panel. The cables are bundled in the basement via a baggie that is tied to them. Inside the bag are a few zip ties, some screws, and standoffs for the motherboard and drives. A few twist ties keep everything in place for shipping.
The cables for the front I/O panel are standard, a single USB 3.0 header, an HD-Audio header, and small connectors for power and reset switches as well as power and disk activity lights.
The opposite side of the case gives you access to the lower chamber, as well as a pair of drive trays. There is a good amount of space behind the motherboard tray for wire management, as well as a huge number of stamped loops for tying bundles of cables down with zip-ties. The loops are even wide enough to use Velcro straps if you move things around often.
Both lower drive trays can be removed with no tools and support either tool free installation of 3.5” drives, or screwing down 2.5” drives.
Cooler Master’s tool free trays are pretty slick, there are fixed pins that line up with the outer most sets of holes in the middle of the drive, which is great as some drives come with only these holes and forego the middle set of mounting holes.
How do you install a 3.5” drive in a rigid tray when the mounting pins are fixed? Cooler Master has an ingenious sliding mechanism that allows the tray to expand just enough to pop a drive in.
If you press the center tap, the tray slides a few millimeters. Then, just slide the tray back closed around the drive until it latches again.
The lower chamber also has 4 raised areas under the power supply to support it, with a rubber pad on each to prevent scratching of the PSU, as well as absorb any vibrations from its fan to keep things quiet. An intake area with a filter feed your PSU all the fresh air it needs.
The case comes with a single Cooler Master 120mm fan for exhaust.
