At work we just ordered a Supermicro CSE-846E1-R900B [1]: 24 hot-swap bays, redundant 900W power supplies, LSI SAS expander. This doesn't quite make a JBOD by itself (it's designed to be used as a case for a whole system); you need to add a PCI-slot-based external-to-internal SAS cable [2] and a so-called JBOD control board which makes the case power up without a motherboard in it. This is the cheapest SAS expander-based chassis I've found; even after adding the two additional parts mentioned above, cost from provantage.com shipped is around $1250 (depending on your location, of course). You'll need to add a SAS controller of your choice and a cable with an SFF-8088 connection on one end (for the JBOD end) and whatever the SAS controller has on the other end. I believe you can daisy-chain this setup by connecting a cable appropriately. These parts are available from other suppliers; provantage is linked simply because they have all of them at one store and the price on the case is the best I've found.
I haven't received all the parts to try this out yet, but I'm confident that this will work as specified. YMMV.
