Hamming is a mini itx type thing donated by User:Aden. It's an old Via something or other and not very good. It's currently running frontdoorbot, hopefully not for very long.
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.
