This is for those of you who ask about this form factor every so often. I hope enough people join so that he makes beige ones.
The X500 Pro is the final product in a line of computer cases designed a few years back (the X500 Plus and later the Evo with a mechanical keyboard) as a tribute to the computers of the '80s and '90s (Commodore, Atari, Sinclair etc...). It's a wedge styled computer case with built-in, full size mechanical keyboard.
