I had the LC17B, which, I believe, has the same internal layout. Excellent case, but I had to go to a slimline case.
As to the question, I think you will have a hard time finding a less deep case with that much storage. The larger cases tend to be designed to allow space for an ATX board, which makes them deeper.
edit: Lian-Li PC-C50 and 60 come close to your criteria.
