Raspberry 4 can be managed remotely by the napp-it cs web-gui
Just upload folder cs_server and start via
perl /path_to_cs_server/start_server_as_admin.pl
# uname -a raspberry4~192.168.2.89
Linux phoscon 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux
ps aux
pi 30136 0.0 0.2 16540 10104 pts/0 S 15:23 0:00 perl /tmp/cs_server/server.pl
pi 30138 0.0 0.1 11192 4880 pts/0 S 15:23 0:00 perl /tmp/cs_server/monitor.pl
Resource needs are ultra low by the two napp-it cs processes on the pi.
Not the perfect tiny ZFS server with USB but should work with self powered USB disks.
Cnances are high that other Arm boards like Odroid M1 with M.2/ Sata work as well
