No gotchas with the Linux install, drivers all happy? Would not touch this with a barge pole with a Shenzen OS, but if it’s plain sailing on Linux I may finally upgrade my old DS214Linux is Linux really. I didn’t need a whole setup as I was migrating from a VM I was passing through a bunch of disks to, to a standalone box so I was already running it pretty bare.
I use BTRFS as a file system on the drives and I’m using mergerfs to balance stuff between the main drives as it’s mainly media.
I did drop a pair of 2gb nvmes in for things like data and my photo library.
