Very sturdy, great value
Very sturdy once everything is fit together and a few pieces of gear are installed to keep it from racking. Heavy gauge steel. Captive nuts riveted in almost everywhere. Many of the parts are reversible which makes it hard to screw up, just pay attention to the numbering and eyelet direction on the main vertical posts. Clever design keeps the overall parts number fairly low, good job from their design team. A bit awkward to build at a few steps since several pieces have to be held in place off the floor to bolt it all together. It definitely helps to have an extra pair of hands or perhaps a few small clamps could stand in to hold things in place while getting bolts started. Overall build is pretty simple, just bolting the corners together. You might consider measuring corner to corner as you put the final grunt on the bolts to keep everything square since there's really no corner/racking bracing, but the its quite close even without this effort. Just about everything required comes with the kit including wrenches for the bolts. The loose nut caster interface will actually require two of the smaller wrenches but only one is included. Not a big deal. One or two steps in the instructions make no sense, like instructing the consumer to put a washer on the back side of an interface then use a wrench to hold the washer while tightening the bolt. I'm sorry, do what now!?!? Luckily it is easy enough to figure out, but I think they skipped proofreading the instructions. A supply of cage nuts and bolts are included, but I went with Rack Studs instead. Despite a few very minor flaws still giving it 5 stars for outstanding value, chonkiness factor per dollar, simple and clever design, and fit for purpose. Open design makes installing sliding rails a lot easier. Great for a home lab. Unless you want enclosed side panels this is a great product. Use the money saved to buy rails, shelves, etc.

Very nice design, sturdy and high quality workmanship.
I had been considering the 8U version of this same rack for quite some time, but when Prime day rolled around, this 12U unit was actually on sale for less than the 8U rack. So I took the plunge because I needed a place to set up a renewed Dell R710 server. It comes with a lot of nice extras that show StarTech has put more effort into its units than most of the knock-offs. It's made of very sturdy, powder coated steel. I really appreciate that it came with *all* of the tools that you will need to put it together -- including 2 wrenches and a Philips screwdriver. The instructions are well written and come in a nice little plastic pouch should you need them again. More than enough hardware included as well. Be sure to measure your server before putting this together. I ended up going about six inches longer because of the measurements listed in the manual. Measure the mounting hardware of your server and make sure you get within a few inches of the fully-expanded rack-mounting. It wasn't too tough to adjust the size, though. It works well with a Dell R710 server (see photo) and I plan to add beneath and possibly a fan/power-strip. It's supposed to be able to hold 1200 pounds and that's probably true. I'm not sure how easy it would be to move with that much weight. It's pretty hefty and the addition of a huge server makes it tough enough to move already. But it's not made to be mobile all the time. It's a good way to get things set up and put it in a cool closet when you are done. I'm happy with this and I'd definitely buy from StarTech again. The quality is much better than what I expected. Solid 5 stars.

Awesome Server Rack for an fantastic price
This rack really impressed me. I didn't have any issues with the packaging and all the parts arrived as expected. The box it came in was pretty thin for how rough and sturdy the metal parts are but in my case it was fine. Assembly was a little difficult because the instructions it came with had images that were kind of hard to see so I just relied on the product images on amazon. There is a part when you have to screw together 3 different metal pieces so the order could be important. It includes tools (actually good quality) to help install however I still needed a wrench to tighten the screws on the wheels which was a bummer. Over all the assembled rack is SOLID. I have a slight warp to it though where my Rack Mac Pro 2019 won't click both sides of the locking mechanism. I have to push the right side in to make it click. Pretty minor honestly and probably easily fixable if I loosen some screws and retighten them. Overall I love this rack. The included tools were great but they need to include something to be able to screw on the wheels because the nut and bolt just spin without holding both sides. The Rack is super sturdy and I have no doubt my Rack Mac Pro, UPS/backup power, and networking equipment won't be going anywhere. I love that It's adjustable.

The rack is amazing for the price. I have worked with a few higher end racks that are closed concept, (in the $1000 range) and this rack is giving those a run for their money. The rack is great for people that don't plan on buying in bulk, (I'm talking 100's) but still want to leave room to expand to a few more of these. The rack comes with ALL the components, screws, and tools to get set up. I personally rack-mounted my 24 port switch, as well as 2 servers, and it's amazing what I found out about this rack. It came with the screws that my switch failed to come with to rack mount the thing, as well as the screwdriver to get them tightened, which not many products do nowadays. The rack comes with wheels for operating, or bolts so that you can bolt it into the floor, the wheels are pretty sturdy for my use. Putting it together was quite a task, but fun nonetheless What else can I say, this rack does exactly what it should and is great quality, with an amazing price tag. Probably one of the best things I've purchased from Amazon.

Ya tenia otro rack de esta marca y la verdad es que muy contento con el EL montaje es muy fácil y tiene la posibilidad de montarlo en diferentes largos. Lo único malo es el precio por lo demás muy buen rack.

J'ai pris la version 25U. Emballage excellent : le carton et solide et renforcé aux arrêtes. Chaque pièces est entourée de plastiques à bulle. Le manuel de montage est sommaire, mais sans surprise. J'ai mis 2h à la monter seul, il faut prévoir un peut d'espace car il est nécessaire de (re)tourner l'armoire pendant le montage. Niveau finition c'est impeccable, une fois bien serré c'est solide et ça ne bouge pas.
