Great idea, but with the dimensions it takes Sharkoon not exactly.

This framework allows the incorporation of theoretically up to four 2 1/2 "drives or a 3 1/2" - and two 2 1/2 "drives.

In practice this is not possible, because this statement of the packaging:
"Fits into standard 5.25" mounting bays "
does not apply.

If the frame with a 3 1/2 "hard disk fitted, so it is already higher than a" standard 5.25 "mounting bay". Taking into account the placement of the screw holes for mounting in the housing, one would have to say more precisely, the frame protrudes down far (7 mm) and up slightly (2 mm) on the measure.
But Another limitation is that two drives can be mounted upside down on the bottom (will not fit the holes), so may not be mounted hard drives, SSDs only.

But what is actually possible?
-------------------------------------
In practice, the frame can then
- Up to four 2 1/2 "drives (. Of these, a maximum of 2 hard drives)
or
- Up to three 2 1/2 "hard drives
assemble, if the bay is free including, if necessary, is also suitable to the lowest drive bay for such placement, as the lowest landing often reserve some space down.

With
- A 3 1/2 "drive plus two SSDs or a 2 1/2" hard disk
can be of any frame in the top slot (Unless 2mm Place Reserve upwards are) installed when the shaft including free or is equipped with a similar 3 1/2 "drive to conventional angles or a card reader.
In other words, the shaft including may not be fully utilized upward, as would be the case with an optical drive, since it must indeed take the 7 mm Overhang this framework.

Without restrictions, ie preconditions to the neighboring bays, is only possible:
- A 3 1/2 "hard drive and pre-bending of the lower boom so that the frame can be screwed sufficiently far down in its slot.
- Three 2 1/2 "drives and partial pre-bending of the lower boom (In this case, the frame does not have to be installed extra deep so, because he does not project beyond upwards).

Conclusion:
======
The frame is well suited to 3 1/2 "disks decoupled in 5 1/4" bays installed when you put it over his heart, rumzudengeln about the frame. In the bottom of my shaft housing in addition it was then possible to mount an SSD to the same frame.
Based on a standard bay, this framework however does not keep all its promises, because he opposed the information is higher than a normal 5 1/4 "drive bay.
