Thecus N2100 (Score 2)

I've got an Thecus N2100 and the performance as a NAS isn't great. The CPU isn't powerful enough to take advantage of the gigE interface. For what you want, I'd get something more powerful which probably means an x86 box. For anyone who just wants a home server that doesn't consume too much electricity so can be left on all the time, a small ARM based box is great. I'm running Debian on it and it's really useful.
