Once upon a time I had a Linux box acting as a home server. It was nice.

Then I wanted a home internet gateway/router and put it at the network edge. That, too was nice.

Then it was slow. Given where it was, that made everything slow. So, I rebuilt it as something bigger than it needed to be and put a SATA RAID in it, a dual Intel server NIC card, and installed Plex server on it. Then it was very nice.
