Intel Xeon upgrade - HP ProLiant MicroServer Gen8
IMPORTANT NOTE, answering a comment below: I only ran the computer without a heatsink because I had to test two processors, and I only ran it until the computer POST and I confirmed the CPU is fine. If I'd have only one CPU, I'd have assembled it directly with a heatsink. Never run your computer without a CPU heatsink and proper cooling for any longer than the required to confirm the CPU works.
In this video, I show how to upgrade a stock HP MicroServer Gen8 to a Intel Xeon E3 1200L v1 processor.
