check out the ECS offerings I build machines for friends and neighbors and these boards are solid.
http://www.pcrapids.com/ is offering a k7s5a board with 1.4 tbird, H/S and fan for $165 + shipping. If you are not going to over clock this is a fine rig. If you intend to over clock get ready to spend some extra bucks on cooling.
board specs
K7S5A, ATX, Socket A, 4X AGP built in 3DSnd+LAN. 266+DDR SUPPORT 5PCI, 2 DIMMs, 2 DDR, 1 AMR, UDMA 100.
Yes it accepts both ddr and dimms, use the extra $ to buy a IBM deskstar, you won't be sorry.
Just remember to disable the modem riser if you do not wish to use the onboard modem, same with sound and lan.
Buy memory from Crucial, again you will not regret your decision. They no longer ship for free but it is still better safe than sorry.
