I have an Intel D865GBF board lying around, with box and all accessories. Only the receipt is missing, but there are signatures on the board and it's still under warranty (more than an year left).
But I've never shipped a package as delicate as a motherboard. I'll charge 1800/- + shipping for that, if you're interested. An Intel Celeron D 320 (2.4GHz; 533MHz; 256KB L2) is also available for 1200/- + shipping.
