I want to use one (or both) of these Dell Optiplexs for mainly retro, and some never emulation.

One of them is a 3060, and the other is a 7010.

I have no experience using an old computer as the base for a build. I've only ever built one pc, and it was from scratch.

I just want to know what I should add to these to make them good enough for my purposes.

Thanks.
