One problem that AsRock keeps messing up the most is power delivery. Using the same, lame VRM over and over again from lesser board quality all the way to the X570. A friend tried running a 3950X on the X570 Phantom Gaming 4 and the VRM was not up to the task under sustained load. It's a 6+1 phase, low quality design compared to Gigabyte's or Asus's 12+2 on their mid-range to premium boards.
Even my X570 Phantom Gaming 4S built 4/6/2020 has 78% power deviation unloaded and 120% under load. The BIOS is missing nice things like undervolt offset settings for the CPU, LLC, some basic elements for a board claiming to be a "gaming" board. It has bad IF splits that don't match popular RAM speeds, few XMP/DOCP profiles, poor overclocking in general. 3 pages with the same settings worded different. 3 out of 5 BIOS updates actually work that they released this year. Sorry but trash. Then they take it off sale for a month and try selling it at $239. Fat chance, it's at $139 right now.
A select few people support them. Reviews I watch show the high failure, poor quality of AsRock. 3 electronic engineers at Level 1 Tech agree and made a table of all the boards with poor VRM's, AsRock is on that list for a few years. Not one board from them passed above mediocre.
None of this matters. OP asked a simple question of which boards might suit OP's needs for a very specific application and workload using a certain CPU and motherboard type. So a reliable mITX for a Ryzen 2700X for light gaming and mostly work, not a huge need for frills or cost. A few options/opinions but not a full scale battle of whether AsRock is worth a salt. OP hasn't asked specifically about that brand so far. I do know for sure that I would not stuff an Asrock mITX into a tight case and expect longevity or a smooth build for any customer of mine. My bad for falling for a sale and trying to save $50.
