This PC was built to speed up my photo editing, but it's also a perfectly good gaming PC.
Horizontally, the cable management bar inside the case limits the thickness of the fans and radiators on the front panel. Some have simply removed the bar, but I like the way it looks, so I avoided thick fans.
Vertically, the total height of the two radiators just barely fits inside the case, but I had to drill four new holes on the front panel to realign the fans so they could fit. I also wanted to mount the radiators in a pull config for easier dust removal, but the front I/O panel at the top got in the way.
