FWIW
I have taken a bunch of 300PL IBM machines - you can get them stripped down
as cheap as $19.00 at the shows - no drives, no memory.
They do have on board video (HORRIBLE), but have an NLX AGP slot, on board
sound (crystal audio, not bad), on board 10/100 Ethernet (Excellent), two
USB ports and all the standard ports.
With a BIOS flash, you can use a one gig P3 (100FSB) or a one gig Celeron,
or the 1.4 gig Tulatin (Celeron) from PowerLeap.com
It can take ANY hard drive (I am running one with an 80 gig and two 40 gigs,
no translation software required).
Coupled with a 64MB Gloria 2 (Nvidia Quatro) video card, it is an awesome
system, fast enough for video capture and DVD burning.
Just a tip if someone wants to build a CHEAP fast system.
