Top electronically, mechanically flop

Since my motherboard still has no USB3 connection, I allowed myself the Delock 89315th was now very advantageous that I with his two USB3 inputs could connect directly via the 19-pin header the card reader clean boost.
Now the problem began. After removing the old Delock 89243 (USB3 card with 2 ext. Standard sockets) I tried einzusetzen.Das the new card was not mechanically, because the distance between slot cover and circuit board contacts for the PCI Express bus of the motherboard was about 1.5 mm longer ,

So unscrewed Slotblech and so once tested the functionality. Was very happy with Win7 and Linux. Since I had no desire to claim the card due to the relatively small price, I feilte slots in the bracket (1.5 mm displacement).

Now it fits. But you can not expect every customer. 65.7 mm (see photo) would have been the right amount. One recognizes it immediately to the two USB3 sockets, which are planned for the slot, but actually 1.5 mm would stand out.

Should a customer try the card with great force to use, there is a risk that the card is damaged or even worse the motherboard.

I wonder if my card is an isolated case or other customer fared just as, beyond my knowledge. The manufacturer was informed by me.

Have the card anyway granted 4 points, because the electrical properties as well as the 19 pin. Header port are well managed.
