It's a pretty old 3GHz Pentium D. It's already a file server (software RAID5 across 4 SATA internal disks), and the only other thing it's going to be doing is the backups.
It's old and slow in modern CPU terms but I'm assuming its still way more powerful that whatever CPU I'd find in a dedicated RAID NAS box?
That is true...however a dedicated Raid NAS box wouldn't have the overhead of the drives being on a CPU bound overhead....md on its own isn't so much of a drag on resources...md talking to 4 USB drives may be. :)
