I've been looking through that list, and I can't seem to find a cheap board that has either AM3 or 775 sockets with DDR3 memory.
I was able to find one with DDR2 Memory, but it's pretty expensive to buy the RAM.
Know of any other motherboards I could use that support DDR3 memory and are rather cheap?
I'd like to keep it at $300.
Would what I posted up there not be compatable with ESXi?
