It's a Chinese-made IBM ThinkCentre Adding Machine. Might be a Difference Engine, too, I'm not sure. Even after Vista came out I've still been sending in those error reports to Mircrosoft after a program or OS crash. I wonder what they do with them. Nothing ever got fixed, or when they DID make a patch it caused EXACTLY as many problems as it fixed, so I'm guessing they just look at those error reports, laugh their asses off, and go back to abusing themselves over a pile of European currency. Seriously, shine a black light on a 500 Euro note and shudder in fear.
Also, that thing in the lower left is not a coffee mug, it's a sippy cup.
