If it was during the 90's, then it wasn't. First version was released in 2002.

ZFS does a lot more then just LVM+Ext4. But it really needs multiple disks for
all the anti-corruption features as well.

If you can keep it between optimal temperatures (and stable) the NAS should
manage. There is NO need to keep it at 18C (like some places do).
Also, consider a small AC unit that only cools a small box big enough for the
NAS. No need to cool an entire room.
