Recently picket up this old Thinkpad T30 for 2 bucks at a local flea market. Its a bit scratched up and the battery is more or less dead but everything else is working fine. Its Pentium 4M, 1gb of ram and 40gb hdd might be a bit overkill for win2k but its really amazing. Running Firefox 13 and a webone proxy to deal with ssl issues.
Some more photos:
With 1024 megs of ram I guess you'll be able to run roytam1's new browsers (K-Meleon, NewMoon27/28, IceApe-UXP, etc) using Win2K extended kernel as well. (win2k.org)
