Well -
Installing Win 2000 needed some 'tweaking'.
You have to make a new CD with SP4 slipstreamed into it to get the early install to recognise the SATA drive as a boot disk.
So while I was at it I slipstreamed all the hotfixes, DX 9, IE 6, and a few other things into it.
So the very first proper fire up into Windows 2000 includes everything up to date

.
Tried XP on it also, installs normally, didn't get any problems with the spinning clipboard (remember to install the two AMD fixes in the sticky).
Had to go back to Win 2000 as I need access to a Dynamic Disk, or buy XP Pro.

Hi res pack
All eye candy to the full
Never moved below 50fps, stayed pretty well pegged at 59fps (60fps = monitor refresh rate)
Should add -
Takes less than 5 mins to install XP or 2000.
XP booted to desktop in around 20 secs, Win 2k a little longer.
