Yes, I'm in the UK - i've seen the rebate deals and will buy a N40L probably next week after I get back from Nice.
Thing is all my systems are basically inaudible, including my office machine. All have big CPU heatsinks (Scythe Ninja's etc) and fanless psus. I really really hate the hum of computers.
However, with IPMI and the small form factor, I'm not sure I can resist. My UnRaid machine sits behind my TV atm and my sofas are around 8ft from the TV so I expect the sound would not be an issue.
The only thing now is that my setup is 5 x 2TB + 1 x 3.5" cache drive. I think i'd have to replace the cache drive with a 2.5" drive.
Also, I'm not sure how easy it will be to transplant my unraid from 1 machine to another. I have no idea if it's all just plug and play these days! Or will I have to fiddle with the unraid disk stuff..
