So, I have recently replaced my 5-year-old laptop with a Dell OptiPlex 5040 SFF, it was cheap and good enough for what I need but I'm wondering if I can do a little more with it.  Namely adding a graphics card, but the space for one is rather small. So, I'm wondering what will fit. Compatibility isn't my question as that's a lot easier to figure out. If anyone has dimensions/measurements I could go off of that would be greatly appreciated. Or just card suggestions. I will remind everyone that I only have a 180w power supply, and the card would have to be one port SFF. It doesn't have to be super powerful just something that works.
