I've recently picked up a Supermicro CSE-846. I bought this rack and these rails.

As the rack was adjustable, I figured it was as simple as setting the rack depth to the same as the server (26") and then installing the rails. However, the rails appear to be longer than the rack. I struggled to find any helpful tutorials or installation documents for these rails and server.

Also, in the instruction manual for the SC846 (I think that's the same server?), the inner rail doesn't extend past the end of the server. Have I done something wrong?

Bonus question, the screw holes on the server and rails don't seem to fit M6 screws, are they M5? Will that still work on the rack if it came with M6 mounting screws, square nuts etc.?

Here's a couple of pictures of the rails. https://imgur.com/a/4m0DkRW

Your rails are too long/your rack is too shallow. You either need rails designed for a shallower rack, or to somehow shorten the outer rails to fit your existing rack.

So I also bought this chassis and it came with a rail kit however i believe this could be the wrong kit and its driving me crazy. I have completely disassembled my lab

i have the rails featured in the third picture found here.
