A Closer Look - Inside

Take off the main side panel once the two thumbscrews have been removed to access the interior. There is obviously not a lot within the chassis as the bulk of space is for the motherboard. Removing the side panel will reveal another spot for a 3.5" hard drive. You must also remove this single cage for unobstructed access to the interior of the Cooltek U3.


The front I/O PCB is held in place by two clearly visible screws. This also holds true for the power button PCB in the top of the front. Due to the compact nature of the chassis, these may get in the way of things when installing a mATX motherboard, which would mean removing the PCBs first—this may hold especially true for the power button PCB.


As we have noted before, the floor of the chassis is where you will be placing your hard drives. If you are installing a dual-GPU configuration, you may be force to use 2.5" drives in this area, though.


Turning our focus to the rear of the chassis, the motherboard-expansion slots are at the very bottom. Above that is the aforementioned fan and the little fan controller, which also utilizes a PCB. The PCB is a neat little addition because it allows you to swap the cooling unit out without losing the ability to control fan speed. The power supply bay in the very top comes with a little lip, which should aid in installing the unit within the Cooltek U3.


All the cables of the U3 are sleeved black and of the standard variety. As there is no reset button, you will not find those cables either. Both audio and USB connectors are of the standard variety, but a USB 2.0 plug would have been a nice addition as well.
