I was thinking of building a NAS/Home server around this motherboard http://www.asus.com/.../E35M1I_DELUXE/
I have the original N36L microserver and whilst it's a nice bit of kit especially considering what it cost at the time, I can't leave it running as otherwise the noise drives me nuts. (It's in the bedroom and I can't easily move it)
The only reason for picking that specific board is I already have it in a HTPC that's about to be replaced and since it's passively cooled and has a reasonable number of Sata ports it might make a good candidate for a server build.
Hoping I can get away with a setup that uses a large slow spinning fan, ideally linked to a temperature sensor so it only actually turns on when it's needed.
HTPC is in an Antec ISK-100 case so all I'd actually need is a new case/PSU.
Not bothered about hotswap drive bays or anything like that, just want something that's quiet
