This is a great case for Mini-ITX motherboards. However, it turned out that my vertical cable was defective. It requires a full-size ATX power supply unit (PSU). However, I think the small form factor would have given me even more space. I used a fully modular power supply, which made things a bit easier. If you want to install 120 x 25mm fans on the top of the device and use a full-size PSU, you won't have much space. If you need a fan on the bottom, it should be 15mm. When you install the motherboard, the adapter cable runs under the motherboard, bends, and connects to the PCI-E slot on the board. ======= Update === I lost one of the screws during installation and the manufacturer was kind enough to send the kit for free!
