Terabyte Storage Solutions?

DeMechman asks: "As many on Slashdot may know, storage is one thing which you can never have enough of. Given the current situation with CD/DVD rot (Personally I can attest to a 10% attrition rate) hard drives in a RAID configuration seem to be a better and more economical solution. If you own more than fifty CD/DVDs, it can be a daunting task to find a file. I am wondering if anyone has found a hardware solution that can inexpensively be set up to handle 10 or more 250GB HDDs in a RAID configuration. Primarily, has any case manufacturer tackled this niche market yet?"
