You could get a regular core 2 system for much less and still use the ECC ram (highly recommended). The case you're looking at only has 6 hot-swap bays according to the manuals, although the pictures show 8 (???). You could shave some off the case and cpu, upgrade your 3081E-R to an ARC-1222 for $200 more and have the hardware raid option. If I was building a tower system, I'd put together something like this: Case with 8 hot-swap SATA bays ($250): http://www.newegg.com/Product/Product.aspx?Item=N82E16811192058 Or if you prefer screwless, you can find the case without the 2 hotswap bays and use an icy dock screwless version. Intel server board (for ECC support) ($200): http://www.newegg.com/Product/Product.aspx?Item=N82E16813121328 SAS controller ($120): http://www.buy.com/prod/supermicro-lsi-megaraid-lsisas1068e-8-port-sas-raid-controller-16mb/q/loc/101/207929556.html Note: You'll need to change or remove the mounting bracket since it is "backwards". I was able to find a bracket with matching screw holes on an old nic and secure it to my case. It uses the same chipset as the more expensive 3081E-R, if I remember correctly. Quad-core CPU ($190): http://www.newegg.com/Product/Product.aspx?Item=N82E16819115131 4x2gb ram sticks (97*2): http://www.newegg.com/Product/Product.aspx?Item=N82E16820139045 same SATA cables for sata to mini-sas, same CD burner. Total cost probably $400 less, which you can use to buy some of the drives. For my personal (overkill) setup I have a chenbro 4U chassis with 16 hotswap bays and mini-SAS backplanes, a zippy 2+1 640 watt redundant power supply (sounds like a freight train). I cannot express the joy I felt in ripping out all the little SATA cables and snaking a couple fat 8087s under the fans. 8 of the bays are dedicated to my media array, and the other 8 are there for swapping in and out of backup drives mostly, but the time they REALLY come in handy is when you need to upgrade your array. Buy the replacement drives, pop them in, migrate the pool, and remove the old drives. I've been running with this for almost 3 years. If I had to do it over again, I probably wouldn't get the power supply, it was more expensive than the chassis and I don't think it has ever "saved" me from anything (although I can't complain, it runs 24/7 and never had a glitch). If I could find a good tower case I might consider it, but I've never seen one I liked with mini-sas backplanes. Really the only thing I'm missing is a nice 21U rack on casters, then the whole thing disappears into a corner humming away. --3224958491-2097000650-1266159572=:26040--
