I am running BraiinsOS on 10 S19 Pros 100Th and find it pretty nice.  Beware that you use smaller SD cards (not larger than 8gb) as they don't play well.  Also, if you get a low quality SD card, you will be pulling them out and replacing them, so in an immersion cooling situation, that is annoyingly messy.

I use stock PSU's and do not overclock alot (3100W) and find them really stable, absent the SD issue.  The immersion mode helps avoid fan simulators if you go that way.
