Re: Horizontal case for a file server

sorry for the late reply; i only stop by here sporadically. another option to consider: AMD socket AM3+ processors. they support ECC, and a cpu + micro-atx motherboard is half the price of a comparable xeon E3 cpu + motherboards. i've built half a dozen systems using ASUS socket AM3+ motherboards wi...

Why bother with a hard disk drive? Boot from USB flash and you could have a system with no moving parts. since i want to experiment with software, i was concerned that i might end up with something that writes to the disk periodically and thus wears out something like a USB drive. this may very wel...

i agree with all your criticisms.
the A03 is inferior to the NSK-3480 in every way, including looks.
but it is encouraging that they'd make one with this small a footprint; let's hope that trend continues.

well, i decided to experiment with Q-fan, but i was unable to scare up a pwm fan, and the MB doesn't do any voltage control on the CPU_FAN header (i tried). interestingly, when i turn on Q-fan, the BIOS undervolts the CHA_FAN connector. not sure why it does that, but it is just a constant undervolt:...

i'm not up on the pros and cons of thermal adhesive. the fanless ninja will cool the CPU fine, but something like a zalman CNPS-7000 or CNPS-7500 might blow some air over the NB. maybe the stock NB heatsink would work OK with one of those. you'd have to be diligent about keeping dust out of the zalm...

one other little detail that probably most people who read this already know, but somehow escaped me:

if you just put ECC memory into these boards without paying attention to the BIOS settings, it will run just fine, but ECC won't be enabled! you have to enable it manually in the BIOS.
