Probably something with a 3080 and at least a 5600X.

This has a 5800X, it's listed $570 but msrp $450. 3080 is $700, Lancool II Mesh is $100, total $1850, you should probably buy an AIO, 360mm if possible, put it front intake. Use the extra 3 fans as 1 rear 2 top exhaust.
Buy a couple extra fans to use as intake on top of the psu shroud. You have yourself a nice cool gaming monster
But, make sure yiu get the msrp, $450 for the 5800X and $700 for the 3080. Prices are very high rn as
@Djoza said, not a great time to build, yiu can tell by the $570 listing for the $450 cpu
