Rebuilding old Dell Optiplexes for home use is common, because Dell Optiplexes are so easy to get and cheap. But there’s a problem if you want to put an Optiplex board in a standard ATX case, whether it’s to make the computer look less corporate, or because you got the board really inexpensively without a Dell case. Dell uses proprietary connectors. Not only that, the connectors aren’t even consistent across different models, even in the same generation. Here’s how to deal with that so you can do a Dell Optiplex case swap, and put a Dell motherboard in a new ATX case.
While Dell uses the standard ATX mounting holes in its minitowers and even its desktops, the front panel connectors are completely nonstandard, and sometimes the power supply connectors are too. Fortunately you can get adapters.
