Looks pretty nice. I'm in the process of doing the same. One bit of annoyance is that I have a half length cabinet but one of my servers is full length.
So here's another homelab sin I committed... I dont use rails. I stead I buy these adjustable universal shelves that get installed like rails. Why? Because all my servers are second hand and require proprietary mounting rails. The dell server rails are way more expensive than they need to be haha
