Rebuilt the computer a couple of weeks ago.
The innards of the old one were around 4-5 years old. Pretty much ancient in computer years. So the new one is a dual-core Athlon 64. Oodles of memory and a reasonably high end video card. The ultra-quiet power supply recently failed as well, so also had to be replaced.. Most impressive thing of all is that it started first time once I put it all together! Surprising since when putting it together it looked like an explosion in a cable factory.
