I have a couple of 'flavors' of 2000 if you dont have any Thor. I dont think I have just plain 2000 originals though. I have 2000 Pro, 2000 Standard Server, 2000 Data Center Server and 2000 Advanced Server. Of the 2000 Pro's I have one that I slip-streamed Sata drivers onto. Another that I have slip-streamed SP4 onto. Another with XP Icons and DX9 slip-streamed onto it. And one more Pro with Windows 7 wallpapers and Icons, SP5 and 400 hot fixes slip-streamed into it. A little mish-mash from my slip-streaming days. 2000 is a rather hearty and stable OS overall to 'play' with.
