One thing to know when going to install Windows on the machine. If you eventually decide to see Windows installed onto a sata drive and want that to be the host and boot drive first unplug any ide hard drives since the master boot record(mbr) as well as the boot files will be placed on that and not the intended sata drive.
If you later decide to dual boot two versions of Windows you also want two of the same type of drive to avoid problems if you don't split a drive into two primaries. With 2 ide models and 2 sata drives seeing 3 versions of Windows on the last build(XP Home/Pro and Vista) and up until lately Vista on an ide and XP on one of two sata models I know that one well.
Once you see the ide drive in plan on a fresh start preferably on a new fresh primary to see a good clean install with all of the hardware and software drivers for the new board(totally different chipset) as well as others things like video, sound, etc. to see working results. That will also see any leftovers like now useless temp folders and old installation logs cleaned up.
