Xeons are big. And they slot into the motherboard much like a NIC. To prevent movement of the CPU and to ensure a snug fit, a retention device (basicaly, it's a rack) is used. Optionally, you can add fans. I got mine courtesy of Terry Hughes. The fans on the bottom of each had to be thinner than the top ones to avoid components or plugs. Terry wired these fans up to a regular disk drive power plug.
