I want to set up a file server on my home LAN with just consumer-grade

going to get a refurbished mid-range tower with a four to six 3.5"
SATA drive capacity, and put WD Reds in it.
What I'm not sure of which filesystem to use. I could just use ext4
with RAID5 or RAID6 to get striping with some fault tolerance (i.e.
time to replace a failed drive without losing everything). ZFS looks
easier, but only if you're on BSD. btrfs sounds like ZFS for Linux,
but it appears to still be of beta quality, and I can't tell whether
it can yet do striping with parity. Any advice?

I just built a second media server to house my music collection, I
collect live recordings of the Grateful Dead, Phish, etc. I used Debian
10 (buster) with six 6TB drives and ZFS. The ZFS pool is configured as a
zraid 2 which is the equivalence of raid 6. The key with ZFS is memory.
My system has 64 GB of ram.
The document I used as a guide to set this up is
https://wiki.debian.org/ZFS
Two things I would advise when using ZFS is 1) never let the filesystem
get to more than 80% full and 2) run a weekly zpool scrub. Mine runs our
of cron.
