I've got three Intel 4 server in 2U (12x3.5") with 2x e5-2670 inside each. Doesn't have ram and limited IPMI, but got rails and two psu each.
Don't have RAM now, don't think will have spare. But ram is cheap (4GB - DDR3L 1333MHz for ~4-5eur /each.
If you interested PM me, I could sell for shipping price and some extra coins for servers. Just need to get shipping boxes... Shipping from EU, but will need to find proper one, because all I see is about 250-300 Eur per server...
