Very true, one machine I had only had 100BaseT, so I installed a PCI gigabit card (no PCIE in this machine). It went faster then the 100BaseT adapter, but the most I ever got out of it was 40-50MB/s (less if the PCI video capture cards were doing something).=20 > Fanless means your drives fail in a year.

Not necessarily. If you get a motherboard with a couple PCIE slots, and add a couple 4 port SATA cards (can be had for about $20 locally), you're set (this is assuming the MB has at least 4 SATA ports, most have more). You would have to upgrade the power supply, and have a case to hold it all (with proper cooling), so the price will ramp a little for that. But still, if you don't care about looks (buy a $40 box fan then blow it at the open case) you'd have something workable. I'd though have to question the requirement of "12 drives". As with everything, a cost/benefit type deal has to be calculated. For example, if the op was planning on using 12 1TB drives to save money, considering the additional costs, it might be worthwhile to use 6 2TB drives instead.
