Got out my soldering iron, scrounged up a couple of LEDs and resistors from the junk box, found a couple of pretty switches and made a mini fan control panel to fit in the spare stiffy bay.
Looks cute. Drops the CPU/mobo temp a bit too. Extra noise of course until I can find some quieter fans.
Seems quite stable even with a bit of timid overclocking.
Now for a play with the RAID.....
