He can do anything, at least what I wanted to do: I ballooned to 16 GB of RAM, have topped a RocketRaid 620 (eSATA FBS mini price) and there have attached a Lian-Li EX-503 which can contain 5 discs. A small SSD in the ODD bay for the OS and the images of VMs (OS: CentOS 7 VMs: ubuntu + other learning VM). Currently a btrfs FS 8 offsuit discs (6 * 1 TB, 2 TB 4 *, 3 * 3 TB, 2 TB *) allows backup of all my other machines (CrashPlan) and storage probably full of unnecessary files; -) As needed, I can free (empty) the smallest drive and replace it with a larger one. Virtualization, NAS, VPN, Web Server, ... I almost trouble finding what to do with my other machines now. I have a N40L in case ... but I hope the N54L still held for many years.
