Supermicro Server hacking - Failed

This is a hack, but not from software point of view. It is some hardware.
I wanted to put a 2.5" SSD into the Supermicro's 3.5" hot swap drive carrier:

Disassembled the carrier, and the problem can be seen right from the beginning:

All 3.5" drives has three holes on each side. In most cases the middle screw hole isn't used.
The carrier has no hole there. But the 2.5/3.5 conversion tray need that hole.
Hole missing, so drilled it:

The carrier also has spring inserts, what also need that hole. The spring is a very thin material. I tried to drill a hole into it:

FAIL!!!!

Ok, I still have other unused carriers, so next try. What if I mount the conversion tray before putting in the spring insert, and not drilling it at all.

Lets try:

Ooops, these screws are to long. I can't cut them while it is in the tray. The cutting will be way too hot for that plastic.
It took a while, to find out, how to secure these screws into the vise to cut them.
Finally succeeded.
At that point I assembled the whole thing perfectly. When I tried to find some screws to secure the SSD into the first thing I found the screws perfectly fits in the place of the recently cut ones. :@

Finally I tried to insert the carrier into the servers cage. Didn't fit in. I found out why:

FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! FAIL!!! 

I'm a complete idiot. I hadn't checked this in the first place.
