It's not stated if the size of your 390 is an MT, DT, or SFF. It's also not stated if you plan to get another 390 case or something aftermarket.
Dell is very proprietary. The guts of a Dell PC won't fit into an aftermarket case, or case of another brand. The wiring is also proprietary.
Dell MB diagrams aren't available for download. Again, proprietary. How else would Dell be competitive?
MB layouts are in the tech guides: Optiplex 390 Tech Guide

Refurb was going to be my next suggestion and I didn't type it.
4-digit model #'s, like 7010, 7020, 9010, 9020, etc., are newer than 3-digit.

MT is the biggest case the Optiplex 390 comes in. Did you mean "DT" or SFF"? If you have one of those 2 sizes, it's entirely possible to change to an Optiplex 390 MT case. I don't how well the screws will line up going from SFF to MT, but there's a better chance of things lining up going from DT to MT.
