OK. Second thing today that I would have never thought existed. That case is cool but crazy.What about a mITX case that already has six 2.5" hot swap bays?
Thats ok, they have only existed for 20 years or so.A hot swap dock that sits in a 5.25 bay? It would honestly never occur to me that such a thing existed. One of the many things I like about lurking around [H]
The 6x2.5 unit I have in one of my PCs has fans on the back and it's still shallower than the optical drive.The good news is a 4x2.5 unit isn't terribly deep.... but that's usually the deciding factor. So... if it has fans (for example) on the back.... it might push the depth.
True but if you are going to stuff 16 2.5" drives in a case today they are most likely SSD's and those are 7mm most of the time.Be aware that the 8 in 1 or 16 in 2 converters can only take drives up to 7mm thick. Cages with fewer 2.5 inch bays per 5.25 inch bay can take thicker drives.
The Silverstone KL06 linked above is 32L
They also make the SG02 and SG11 which are both 22.5L. There should be a few media center style cases (lay flat, about 5-6" tall but very wide and deep) which have one or two 5.25 bays, but I can't think of any off hand.
Note that the SG cases will be pretty tight to work in (though those look like they have a bit more room than my 10.75L SG06, looks can be deceiving). Since you'll be using the front bays, you'll probably not have as much room for a cpu cooler or gpu, depending on mb layout and case design.
Edit: The Apex is under 10L...wow.
