Silverstone SST-RMS07-20 Rackmount Rail Kit - For SilverStone RM400/RM41-506/RM41-H08/RM42-502/RM23-502-mini

I don't know what the previous review was about but it is compatible with RM23-502 Mini and I have it mounted, one slight caveat is that it doesn't use all 8 mounting screws to attach to the sliders, but uses 6 instead but it's still pretty damn sturdy. I have stressed tested it by applying extra weight on top without so much as a squeak and works as expected.

This product is supposed to fit a number of Silverstone chassis, including the RM23-502-mini which I previously purchased. This in reality is impossible because only one hole on each side of the chassis line up with the rails in the case of the RM23-502-mini.
The instructions for separating the rails provided in the instruction manual appear to be for a physically different type of rail than the RMS07-20 and there is no obvious way of achieving it otherwise.
It also appears the chassis cannot be completely removed from the rack once installed without disassembling the rails.
Overall this purchase appears to be a complete waste of money. This product is supposed to fit a number of Silverstone chassis, including the RM23-502-mini which I previously purchased.
