There's a "HP EliteDesk 800 G2 Tiny i7-6700 3.4GHz" that can be had on ebay for around $200, that's a pretty powerful little box. My son had no problems using it for light gaming. Note that these can get a little toasty under long, heavy use and throttle, just because of the size. My one that does camera processing seems to need to run without the case on.
