According to the manufacturer’s specifications, the case may accommodate very large components: a video card up to 375 mm (or 400 mm in the absence of the front fans) and a power supply of up to 200 mm in length. CPU cooler may be up to 165 mm high.
Despite the construction of Aerocool P7-C1, the power supply is placed in the most common way, and the board is set to the standard six-millimetre racks. The thumbscrews for fixing it are not supplied.
Let’s have a closer look onto the drive installation. The carriers for 3.5" storage devices are simply stretched on hard drives. They are to be straightened a little to be installed. The 2.5" storage devices are attached to the carriers’ by cogs, and it is possible to mount them not only to the ends, but to the ground as well.
The carriers with the mounted hard drive are simply retracted and sit in place securely enough. And the solid-state drives are fixed to the carriers by thumbscrews.
