Just saw a tweet from a friend and thought that I'd do the same thing.

Allyson was built in October of 2004, and was given to me by her previous owner after a hard drive failure. I've added the 8500GT in place of the stock ATI X300 and the FX5200 to run the 15 inch LCD. So, in the year Allyson's been here, I've "invested" about 140 dollars between the two video cards and the 15" LCD. Lovely machine, even if I had the money I don't think I'd replace her anyway.
