I have an IBM x3250 M4 1U server available but its missing some key bits. I believe its model 2583-62M

It is missing the HDD, but it does have the blue caddies.
It is missing the CPU but should support a range of 1155 2nd Gen Sandy Bridge CPU's
It does have good MB, PSU, 4GB RAM (2x2GB), RAIL KIT and was working fine until I removed the CPU for another project :-)
If anyone could find a use for it I do have the original box to ship but collection is preferred. I am in Albany, Auckland.
