The problem is that my 3,5" drive cage in my Chieftec Winner(like Dragon inside) case is shorter verticaly than horisontally..
1) Mount them up in an empty 5.25" bay, if you have the space.
2) Suspend them below the 3.5" HDD bays in a spare 5.25" bay enclosure like the one shown in MikeC
's pictures. Just lay this bay on the floor on the case sitting on a piece of foam. Throw a quiet fan in the front case wall to blow cool air over the drives (as they tend to run hotter when suspended due to the lack of the "heatsink effect" of being hard-mounted to the metal case).
