The best part is installing the computer hardware. In comparison, obtaining the system fans is somewhat more difficult, since you don't have many choices for the 120 mm versions. We were able to install the motherboard, the drives and the power supply without problems. During installation, even larger hands have plenty of space for maneuvering inside the U2UFO.
Power supply: Placed comfortably on the chassis floor.
Motherboard: Can be pre-mounted externally on a tray.
Drives: Infinite room for wiring.
