Avoid getting 2nd hand motherboards as the capacitors have a fixed lifespan. I think you can still get socket a boards from greenhills. Try Ace Net at Shopsville or V mall. I was able to source some of the the phased out motherbords and hard drives from them as we still have some of the older pentium 3's and celerons here at the office. For socket A, I got a msi nforce2 motherboard around february this year.
