Ryzen 5800X Upgrade Build Report & Lessons Learned

This weekend, my 17-year-old son and I did a partial refresh of an ATX form factor build. We swapped out the old motherboard, CPU, cooler, M.2 NVMe and RAM for a new set of similar components:
1. Asrock B550 Extreme4 mobo
2. Ryzen 5800X CPU
3. 2x32GB DDR4 2600 G.Skill RAM
4. CoolerMaster 212 Black cooler

Time to complete build: around 4.5 hours, of which 2 hours for disassembly and cleaning and 2.5 hours for reassembly, build and initial test

Results: success all the way around. Still need to enable fTPM in BIOS to be Windows 11 ready, but everything else is copascetic for Windows 11 installation.

Lessons learned:
1. Had to use Diskpart to set the partition layout to GPT before Windows 10 would install on the drive
2. Coolermaster 212 is a very TALL cooler so had to remove the side panel case fan to get clearance. May be able to rejigger that, though in a different position. Will check temps first.
3. Learned the hard way (should have RTFM) to use the M.2.1 slot for the NVMe because using the M.2.2 slot knocks out SATA ports 3, 5 & 6. Making the switch took 5-10 minutes, so no biggie (did have to take out the GTX 1070Ti for room to maneuver
4. No major issues with drivers or boot-up, once the GPT issue was addressed (Used a Ventoy boot disk with latest Media Creation Tool to grab an ISO for Windows 10 21H1 for our point of departure. 7 or 8 updates from WU were necessary to catch the PC up after that)
5. The new PCIe Gen3 x4 NVMe driver (Sabrent Rocket Q 2 TB) is very fast, the new build runs about 2x the old one pretty much across the board.

Overall, very pleased with the results of this partial refresh. I'll spring for a new GPU when the prices come down a bit more, or we get some kind of windfall to justify the nosebleed prices still prevailing. Does pretty well with the 1070 Ti, though.

Where do you buy that RTFM?
If the side panel is metal, you could grab some 14 ga. aluminum to plug that hole.
Another solution would be a thinner fan... something like... a 12mm thick fan as opposed to the std. 25mm.

It's an Antec 900 or perhaps 902 case, and it seems to be cooling OK based on the 200mm CPU cooler, the 200 mm top fan, and the three 120 mm fans also in the case: one rear, two at the front of each of the two drive bays. Just got the BIOS flashed and it now passes all tests on the WhyNot11 utility so it should be good to go for 11 when it goes RTFM.

This is a school/production PC, so it's on 21H1 production build tracking now and will be upgraded when 11 goes public later this year. The Blackhawk is my personal desktop (main daily driver). It has tons of room and would easily accommodate the CoolerMaster 212 black and all of its case fans (of which I count 7 right now). I'm thinking about the same refresh for that machine, too. Pretty impressed, so far.

Thanks for the input @Ghot and @bobkn.

@bobkn: its primary user (my 17-year-old high school senior) has also been known to play some games. The RAM and CPU are helping his user experience, but we still can't afford a state-of-the-art GPU (too expensive, or impossible to get). So yes, it is a pretty formidable "school machine." Thanks for the input.
