I'm considering buying one, because of the great price. 

Though the advertised specs and features are enough to more than justify the price, some reviews and benchmarks I've read have a very 'mixed' feel about it.

I'll use it for programming and and some heavy tasks on a Linux system, apart from being a home file server, so the argument about 'regular software doesn't utilize threads' is not valid for my case.

So, my question to those who use it, have you observed any noticeable problem with it ?

Apart from that, I'd be happy with general opinions on it.
