I then drill a whole through it in a couple of places and bolt it to the rack. It's not as nice as sliders, but it gets the job done for all the systems I've used in the past couple of decades. It wouldn't work well, however, for systems that have big heavy disk drives, for tape drives, etc. It also burns 1 U in the rack. For me that's not been an issue but others have complained about that in the past when I've suggested this.

This will be going into my Garage, so cooling will be a challenge during the summer. OTOH, it’s really nice to be able to log in via ILO and check the system temperatures. My plan is to keep the 24x7 servers as low to the ground as possible. Stuff that gets powered of “when needed”, can go higher up in the rack. The one exception will be if I put the MicroVAX III with RA7x drives into the rack, like I’m threatening to. Those would probably be forced to go in the bottom.
