PC Components fit barely enough without getting damaged. It was my first time building a PC in a long time, so I really had to be creative with cable management. It may have been easier to get custom made cables to ensure a good fit with a little space, but it's really tight in there. Managed to fit a 360mm AIO and a ASUS ProArt 4080 Super. Otherwise, great looking case and I love the tall but small form factor.
