I'll second that. I have a 5800x and 3070 Ti in mine, runs great. CPU is cooled with an Arctic LF 2 280 AIO, which I wouldn't recommend to a stranger as it's pretty tight and probably not great for the tubes, but the point being that you can fit some fairly beefy gear. Don't think I would would gain much performance with a larger case as with all the ventilation everything is drawing fresh air.
