Building one of these DB4 PC's.
So far,

Mini ITX board: ROG Strix B650E-I

CPU: Risen 8700G

RAM: 128GB (64x2) DDR5 6000 CL30 EXPO

PSU: ZF240 240W passive

HD: 2 TB Samsung 990 Pro NVMe

This is all going to be passively cooled, sealed, not sure if there will be any heat issues besides the CPU with additional coils to push off 120W max from the CPU to the case. Will I be at risk of the memory heat soaking here, or can they run perpetually in a sealed system with no air?

Will be full throttle for hours at a time.
