Cause the hard drives are an upgrade path option. Would still be horribly inefficient before and after the upgrades..
But thanks for the heads up on the low amount of sata connectors..its hard to find good informative websites while shopping for these. Does the one you have have 6 slots?
The problem with the 120W PicoPSU is that you'll need a 120W power brick, which are a bit more expensive than 90W bricks. And I don' think you're gonna need it.
Say the board+cpu+ram takes 20W, inside 80W you have easily the power for 6HDDs (~36W on load). You could buy splitters to power the disks, fortunately I had them laying around in the basement.
About the motherboard, I haven't found any Atom board (except for some ION based) that support more than 4 SATA ports. A PCI SATA card is your best solution. If you decide on this route something based on SIL3114(6) or VIA VT6421 are good controllers, SIL even supports RAID5, while VIA supports one IDE port.
EDIT: Pico-atx PSUs don't follow the same efficiency curve as an ATX PSU, becasue they're simply DC-DC converters. Their efficiency is constant over 90% no matter the load, so oversizing wouldn't be a problem (except from a cost standpoint).Edited by dragosmp - 1/4/11 at 4:26am
