Just watched this, ETA Prime was the perfect guy to review this. Makes me want to run out and buy a Minisforum MS-01 and an A2000. That is a lot of power in a very tiny package. Shout out to @robbee for making a quality product.
Curious what your use case is for the PC. I have a 13600kf and if I am just browsing and watching videos it uses under 15W and when I am gaming it only uses 50-60W. If you aren't doing anything as intensive as benchmarks with your PC don't worry about benchmark temps or watts.
Is there a reason you aren't considering AM5? That is the best platform for future proofing since current motherboards should support 2 or 3 more generations of CPUs.
On Intel 300 series motherboards there are 24 PCI lanes on the chipset and that is what the M.2 will use, the 16 PCI lanes from the CPU will be used for the 3.0x16 PCI slot.
I had a white SM550 for a while and really liked the case. Later on I wished I had gone ahead and gotten the 560 instead. Sad to see the Cerberus go into retirement after all this time and I am just about positive you will find a use to the 4080 FE.
