FML. Just when I finally managed to dual boot win10 and centos, only to just read the news of RHEL change its focus and shift to make me a beta user into Centos Stream. Time to distro hop to Arch.

My current "file/media server" is a crappy old falling apart windows box with a stupid mismash of internal and external drives with no redundancy. That sucks for a number of reasons, so planning on dropping around a grand or so (including drives) on doing it properly.

Space requirement would be around 20TB-ish of usable space, with 1 disk's worth of redundancy. That can include a newish 5TB drive I have lying around however. Would also run either Plex / Jellyfin, so some horsepower for transcoding would be nice (but no need for more than a single 1080 stream at once.) 24/7 operation, so don't want anything too power hungry.

Current (loose) thinking on the hardware side is an AM4 board and a reasonably low end CPU, 3x8TB WD golds. Software side, probably CentOS, then mergerfs + snapraid. Anyone got any insight as to other options? Hardware not my speciality in particular, so open to suggestions.

What do you think about Rocky Linux ? Is it really the "in-place replacement" to CentOS it intends to be? Would you rather advice another alternative?
I've used it for a while now, but not for anything critical, and I have to say I found nothing bad to say about it, but I wonder about your experiences.
