Hi,
Just to keep you informed. I just received a nice ex495 (cpu 2.5Ghz, 1.5TB Windows media server). I'm not a fan from windows but this box is really nice.
Box is nice, no noise at all, 4 slots available. I have the ideas to open it and see if I can install a linux os and some addtional ram. The cost is around $680 which is really less than a thecus. At the end will check the performance too.
Keep you in touch.
BR
