OptiPlex 755 Hacking
I had a old Optiplex 755 knocking around and I wanted to stick a PCIe graphics card in it. Unfortunately the 755 is a small form factor PC and the PCIe card, while electrically compatible, doesn’t fit.
I removed the section around the PCI bay, this allowed the front of the PCIe card to stick out of the system. Unfortunately the heat sink also encroaches on the footprint of a double width PCIe card. So it had to go. The casing around the heatsink and keeps it firmly coupled to the motherboard was removed. Amazingly with the heatsink JUST SITTING on the processor enough heat still seems to get dissipated, well… time will tell, but so far there are no signs of overheating.
I also had to replace the powersupply, there was no way the dinky little thing in there was going to power a double width GPU.
