I really don't think that much horsepower is needed for a media server. Like I said, I don't think I've ever come across a video that a Raspberry Pi can't handle.

Lots of horsepower is only really necessary if you need to transcode stuff to be played over WAN.

For most home media servers, they're basically file servers. Extreme CPU oomph isn't really needed unless you're doing your transcoding on it as well, and even then, a Mini can handle that like a champ. My base 2012 with a 2.5 i5 chews through encoding with no issues.

Well yeah, that's just one of many things I'd like to use it for. Also do lots of transcoding, music and HD video. Would also like to start doing some editing. And would like a machine that I can use for many years without worrying about slowdowns.

Mostly though, going to be getting into some stuff that would be ideal for GPGPU, and this would be a great way to gain that as well. nMP still does 7 tF in single precision and about 2 in double precision (with D700s), and that's still quite a decent amount. For the money you'll pay for a good used one with D700s, you're still getting a lot of performance and reliability. It's definitely not worth the money new, but they are really starting to depreciate on the second-hand market.
