It is a mystery which had to serve for a device to measure me, because neither the width nor the height nor the right holes.
I have a case from Cooler Master with clamp locks. They engage in the bracket but simply ineffective. Only if one fixes the bracket centered in the slot (mean screw from the other side), it is possible there to jam more bad than good.
The holes are therefore in the wrong position.
An additional problem is that approximately 3mm missing in width. That is in contrast to eg. A DVD drive which sits crisp in the bracket, the bracket is shaking loose around.
The height of the bracket is as mentioned also curious and is 2.5 cm which somehow bears no relation to the amount in a 5,25er bay.
Also interesting is the supplied vibration dampers. Where it would make sense for disk -So, let not be used for reasons of space only.
Who has the power to screw the bracket on both sides and only want to attach an SSD can probably live with the shortcomings. With clamp closures in case the handling is quite underground.
