You could actually fit a small RTX 3060 Ti in this budget mini rig, and it would game like a hero.
Officially, the case supports discrete graphics cards up to 200mm long, though there is a little more room in there. So, if your intended GPU is a few mm longer than the stated length you can still just about wedge it in. I managed to slot in ASRock's own RX 6400 Challenger ITX model in there with no problems, but if you're looking for more performance and cooling power, beefier dual-fan cards like EVGA's XC2 3060 TI will fit too.
Given that the PSU's bespoke though, we'd have appreciated a bit less excess wiring and a modular cable design, because there's really nowhere to tuck and cable-tie away your loose or unused wires. Cable management did remain an issue though, even after stripping it down and starting it again with a different build.
