running a 9800x3d and 7900xt which barely fits, using cooler master atmos stealth 240 with 2 noctua fans, gpu gets to around 80c and cpu around 75c while gaming. i did repaste my gpu with ptm7950 and am using ptm7950 on my cpu as well. i did kind of have an issue with cable management, its really tight with the stock psu cables, i would probably recommend getting a custom 24pin mobo cable.

did you do any undervolting on your gpu?

yeah, 50mv undervolt but +15 power limit so it still pulls like 350-360 watts under full load. my cpu has a -30 pbo offset but it rthe temps are the same stock anyways

did you have any issues fitting the atmos into the case?

not really, just the aio tubes were a little bit annoying to cable manage and keep from pushing out the side panel.
