Hamming is a mini itx type thing donated by User:Aden. It's an old Via something or other and not very good. It was frontdoorbot at one point.
It's also connected to some speakers so it can do the glados voices as well.
It does have 2 x hard drives in RAID1, which is nice. It also runs X and can do TV out (maybe) so could connect to one of the CRT TV's for extra grimy retro ness.
