I don't think it be a poor choice mostly because it only uses about 1 watt of power.
I have the MK808 running as my home server with Linux on it now and 2 USB hard drives that are 3TB each. It's booting off one of the 3TB drives.
Samba is running on it and Apache and they work super good. Nice and fast.
Can install lots of things with apt-get install. I got pyTivo running on it. So my HD TiVo can download videos from it.
Have WordPress running on it and lots of other things. A phpBB message board too.
With Samba it is sort of like a NAS and more right now.
Here is some little info commands to show it some.
