A 60TB NAS

Buried in a corner of my closet at home is a hard-working Atom-based netbook that has been heavily modified over the years to act as a NAS with a grand total of 42TB of storage, 41.2 of which is in active use. It's not a pretty setup by any stretch of the imagination, and I'm honestly surprised the thing has gone this long. As moving day to the new house fast approaches, I'm wondering if this is the moment to spring for a proper machine with a nice AMD processor, a good amount of RAM, and 60TB in a RAID6 array. I also wonder why more people don't have storage servers of their own at home running on older, semi-retired hardware.
