Ah, that’s a good point. The full tower version has space for that, though.

I’m not saying you should get an Optiplex 7050 specifically, but a used office PC tower (like an Opitplex, HP Elitedesk, Lenovo Thinkcenter, etc) can be picked up for under $500, ready to go, and has more than enough processing power to handle the loads you’re asking of it. Plus, they usually have Intel’s AMT management option (aka “vPro”), which allows you to remotely manage the PC even when it’s powered off.
