I have finally gotten the parts together and built my new PC, although, it's currently resting in the other room. I did install WinXP MCE on it, but decided not to use that as I will be using it for my media centre, so I caved and ordered Vista (even though I was going to wait a while, to allow the bugs get ironed out a little).
I was going to make do with 1Gb of memory, and upgrade later, but with Vista, I decided to get an extra 1Gb, giving it a total of 2Gb.
The build was photographed, and will be documented in due course.
