I am disassembling my computer for sale of its parts. It was a custom built (not by me) Gigabyte GA-EX58-UD5 with an Intel i7-920 processor and a Scythe Mugen SCMG-2000 heatsink. While removing the backplate of the cooler, I removed 8 screws, 4 long and 4 short. I'm 90% sure that all these screws were attached to the backplate. (Of course, if they were underneath the backplate there is no way that I could have gotten to them). When I separated the cooler from the MB, the silver CPU socket (CPU holder with the handle) and the CPU stayed attached to the heatsink and not the MB. When I attempted to re-attach the CPU holder to the MB, it is too loose as even the short screws seem to be too long. There are some washers that I removed, but even adding these does not result in a tight attachment. I'm pretty sure that these washers were not used with CPU socket screws anyway as the outer, non CPU backplate holes seem to have some recessed areas around each screw hole for these washers. Adding the thickness of the heatsink backplate appears like it would result in a tight fit, however. I'm assuming that the original short screws which held the CPU bracket had to be removed during installation of the heatsink in order to make the heatsink fit correctly. Do you think this is likely? If so, then the new buyer would have to use the same heatsink or I would need to buy some shorter screws to secure the CPU bracket tightly.
