My main PC was an Athlon700 which I experimented with and had QNX + AmigaXL and Win98. It died shortly after receiving my Peg and has been mostly replaced.
Other X86 machines:
I've got an IBM Thinkpad (bottom of the line when I bought it, added some ram.) I use it mostly as an MP3 player, and for WinUAE.
I've got a P133 system that I use as my scanning, and CD Burning station.
That way I can continue pounding on my other systems happily while burning CD's.
