Hi I don't have any data at all,

Just recently bought and installed the kit. Installation is very simple.
You can install this holder in any case (doesn't have to be CoolerMaster) as long as it has 7 free slots on the back.
Bear in mind, however, that with this holder you will no longer be able to install an external sound card, for example, as (presumably) all slots will be occupied. That is just a hint.

The specs of your case look like this:

Number of plug-in card slots: 8x
Max. Length graphics card: 490 mm

Therefore no problem!

There are also various videos where you can follow the installation very easily. Regarding the benchmark, no more than 1% of performance should be lost with this conversion.
