I am running a:
Dual Pentium Pro 200/256k
stepping 9 overclocked to 233MHz
256 MB EDO RAM (2 pair of 64MB)
Voodoo3 PCI video card
Slackware 10.0 Linux
I haven't booted Win in almost a month since I installed Linux.
I built this machine from almost all new parts in '98. For being a 6 year old machine, it really kicks ass!
I will upgrade when I can afford to. I will not buy another computer on pure credit for personal use.
