This is great little rack. It's solid, sturdy and easy to assemble. The markings on the front and rear rails for RU location are clear and highly visible. The adjustable depth is a great addition. I set mine up for 24" depth, as it sits right next to my desk. The gear I run in it isn't super deep, so that worked out great for me.It comes with all the hardware you need to assemble, as well as a sufficient amount of cage nuts and M6 screws so you likely won't need to supply your own for the first 6-8 devices you'll mount. I did find a couple of the nuts used for assembly had some resistance when initially threading them. There were enough in the bag that I didn't have to mess with forcing the threads and just used one of the other nuts. Not a big deal since there were plenty of extras.I cut some furniture pads/floor protectors to stick on the lower base, so it won't scratch my wood floor if I move it around.As others have mentioned, it is made of aluminum, but it's a good grade of aluminum so doesn't make it feel flimsy. When I mounted a Cisco 2921 router in it, I could see the front rails deflecting just a tad from carrying all the weight on just the front rails. Keep in mind it's a heavy 2U router that is about 18" deep and no rear support.All in all, it's a great rack, high quality, and fits my needs perfectly. I even made a nice oak top for mine so I have a place to put more of my tech clutter!
