Chenbro used to have a couple mITX cases with 4 hot-swap bays which they've since discontinued. These cases were pretty popular for small file servers. Chenbro has a new mITX case out as a replacement (SR30169) that has 4x3.5 hot swap bays plus 2x2.5 internal. The case also looks like it will be much cheaper than the old models. The previous cases cost over $200 while this one is around $100-150 online.
I haven't found any reviews of it yet and would love to see one.
