Yeah, 8 GB should be enough for standard business or personal use.
I assume you don't have intentions of "re-building" the PCs or getting inside the case much. If that's true, there's nothing wrong with smallish cases and micro ATX motherboards.
I'd probably try to tell you to avoid anything ultra-small--like the size of a six pack or something. Too many compromises, too limited in options, etc. Get something semi-standard--tower, mid tower, mini tower, whatever.
If you can pay 650 each, I'd certainly think you could find something with an SSD, unless maybe you have to buy within 24 hours.
