Can't do that, all my tests so far indicate that if anything is something other then vista performance drops severely. I've tested with linux, xp and vista. Whenever a client or server is something other than vista, transfers cap at about 100mbit speeds.
Right now I'm thinking of replacing the stock lian-li 120mm intakes with 2 silverstone I have that push quite a bit more cfm.
I'll see first if my thermaltake is any better for hdd placement but I don't think so.
If the antec titan 650 wasn't so expensive I might fetch it just to avoid having to convert the deadspot 5 1/4 inch bays but even in the titan I'd have to do so.
I might get freenas to retest since my linux part was a synology nas that's just underperforming but I won't bring my hopes too high, I don't think the results will be much different, the same vista server I built to a vista client goes full drive speed (50-100mbytes/s) while with the same client dual-booted to xp drops to 10-20mbytes/s.
How were you planning to get more than 100mbit on ethernet unless you're using gigabit ethernet? Firewire for that many drives will not work unless you just make the thing run windows with all the drives shared, and that's a lot of work for nothing really, and a lot of hardware for a simple job. XP would work too, still overkill. Start downscaling the idea of an OS and start thinking of other solutions. I use FTP to my NAS here in my house to pull files off the drives, otherwise the thing craps out midway. The CIFS isn't really designed for large file moves in a timely fashion, it's only designed as a stop-gap to please consumers. FTP is way more reliable and quicker.
