yes, choose 747 as suggested - a bigger case with bigger fans. and yes, you can buy chassis only - it a case with dual PSUs and and 8HDD hot-swap bays, so yes, it can hold your HDDs. and then find someone that will do all the diassembling/assembling work for you.I am considering the supermicro chassis (with the 9400RPM fans!) just because it seems built to purpose
