The interior of the Commander MS-I case is relatively common, although Thermaltake made it all black for aesthetic purposes. The disk drives are being placed sideways, facing towards the front panel of the case. There are holes around the motherboard tray for cable routing which should prove to be very useful but there are no rubber grommets. There is a hole behind the CPU area to allow the installation of large coolers without removing the motherboard. This case allows the installation of graphics cards up to 32cm long; however such a long card will also block at least the one drive bay in line with it.
The PSU compartment can be seen at the bottom of the case, next to an optional 120mm intake cooling fan. There is a very basic dust filter over the PSU air intake area which is NOT removable; virtually, the only way to clean it is remove the PSU and blow pressurized air from the inside of the case. The PSU is being seated on a metallic stand (encircled in the picture) which is very sharp and will definitely put a scratch or two on the PSU chassis during installation.
At the rear of the case a semi-transparent black 120mm cooling fan with blue LED lighting has been installed, the only standard fan of the Commander MS-I. Interestingly, the fan’s power cable is sleeved.
Thermaltake is using simple plastic locks for drive installation; on three out of five HDD slots, on two out of three 5.25” device slots and on one out of two FDD slots. If you are planning to install more drives than these, you will end up using screws to secure the drives. An interesting observation is that if you are not planning to install any FDD drives or external 3.5” devices, you can install internal 3.5” disk drives in their slots instead.
Our ICTT system fits in the Thermaltake Commander MS-I case, although tightly. A full ATX motherboard would end right where the drives begin. Installing a very long graphic card will block the slot in line with it; which slot should be the bottom external 3.5” drive slot if you are using only one card. It is not a very roomy case, neither designed for the quick and easy removal of all components, but it certainly fits a normal ATX system inside with ease.
