VEVOR 12U Open Frame Server Rack, 23-40 in Adjustable Depth, Free Standing or Wall Mount Network Server Rack, 4 Post AV Rack with Casters, Holds All Your Networking IT Equipment AV Gear Router Modem

If you are building a home lab or organizing a media closet, the VEVOR 15U Open Frame Server Rack is an exceptional value for the price. The adjustable depth (23''–40'') is the standout feature, allowing it to accommodate everything from shallow networking gear to full-sized enterprise servers. The build quality is impressive for a budget-friendly rack; the 4-post cold-rolled steel construction feels very rigid even when loaded with heavy UPS units or disk shelves. Having the option to use it as a free-standing unit on casters or wall-mount it gives you great flexibility as your setup grows. The included casters are surprisingly smooth, making it easy to pull the rack out for cable management.

First off, this thing is extremely sturdy and totally worth the price, but absolutely cannot be assembled by hand. You will definitely need a high-torque screw gun of some kind, such as a drill with an adjustable torque setting. Although the screw holes in each piece of metal are somewhat threaded, they take a large amount of force to turn into the metal and secure deeply. I had a Dewalt drill set to level 10 torque, and in some cases I had to increase that. Needless to say I was surprised that I did not have one single screw that became stripped out, although they appear to give you about 50 extra screws just in case you have lots of trouble. Don't forget to adjust the torque though, you wouldn't want to have a drill on the drill setting or you'd likely strip out tons of holes. I saw some people who talked about having issues with getting things in alignment, stating they weren't able to get the corner reinforcements mounted. My advice would be to try to leave most of the screws a little bit loose until you've fully assembled everything, including the corner pieces that add stability. I could see where alignment could be an issue if you tighten everything as you assemble it, whereas if you leave everything a little bit loose you'll have some wiggle where you need it. After getting every piece attached, before installing any shelves or devices, tighten all the screws to a high torque setting on your drill/driver. It was fairly simple to tighten everything after the full assembly, all screws are still accessible. I feel like the instructions should tell you in the beginning to leave everything loose, but I didn't see it printed anywhere unless I missed it. The instructions leave a bit to be desired, take your time and study the image diagrams.

The rack itself is nicely made, but as others have mentioned, the M5 holes are not tapped. Although self-tapping M5 screws are furnished, they only work when the holes are perfectly aligned, and none of the corner support holes are. I ended up redrilling to align the holes and purchased some M5 nuts to fasten with the M5 bolts. Since inside corner access is next to none, I have the bolts pointing outwards with the nuts on the outside, and appearance isn't bad at all. As far as the wheels go, they are useless for after installing more than 20 lbs of equipment on them. The wheels are mounted on cross braces, not the frame itself, and the cross brace twists and skews when the rack is rolled. I got rid of those wheels and purchased some nice 4" heavy duty poly casters and mounted them to a 2 foot square piece of 3/4" plywood and placed the rack on top of this platform. Much easier to wheel and the rack is solid after bolting it down to the platform. The M5 bolts worked fine on the top plate but I strongly advise using a power screwdriver unless you have a strong wrist. My power screwdriver had enough torque to work the self-tapping M5 bolts into the frame, only because those holes lined up. Overall a very nice rack if you're resourceful and can work around the gotchas.

For those having difficulty assembling this 4 post rack: Yes instructions could be better on a couple steps, but I'd guess you also have difficulty assembling most items overall anyways. Details are in the pictures on which way to assemble this 4 post open rack. Pay close attention to the pictures at the ends of the pieces, as they are shaped differently and if you note the position correctly, you won't have any issues at all. NOTE: Do not try to drill a hole with the electric drill you will need to use, once the threads are cut immediately stop when the head of the screw touches the metal. Items to note: 1) The height of whatever 4 post rack you are looking at does NOT include the wheels. I bought the 20U model which stated 38.7 inches, and with the wheels on comes in at just under 41 inches. 2) Weight capacity says 500lbs. No way this is even close. Instructions as another has shared clearly says 200lbs max. 3) You are going to need an electric drill with a #2 bit. I used a Milwaukee M12 1/4" impact with a magnetic 4" bit extension and it worked fine. Set on power setting 1. Not one thing can you use a regular screwdriver when installing this, except to mount the 2 included shelves at the end. So if you don't have an electric screwdriver I would recommend the Milwaukee M12 series or similar. 4) You don't get one of those thin flat cheap wrenches for putting on the wheels. If you want to put them on it's a 9/16 or 14mm open ended wrench. Snug is all you need for the wheels. 5) The first step is the most important one, if you intend on extending the depth for you 4 post open rack needs. Instructions mention, but not a lot of detail. I set mine at 32in deep, which leaves 9 open holes on each end as you assemble the depth rails on the first step. Adjust accordingly for your depth needs. 6) Also note, if you need the depth to be over the 23" default depth, the top metal piece isn't going to cover the entire top. I put mine covering the front of the rack which left me with a gap in the back. Screw holes still match on one end, and you could easily modify the back where it ends if you want to. But there will be an open space on one end since they don't know what depth you need if you want to adjust. 7) Wheel thread size is M10x1.5 if you want something more sturdy instead of the plastic ones supplied. So far I haven't seen an issue, but for those putting up to the 200lb limit you might to do something different. Your call. 8) Once you fully assemble all parts, gone through all the steps - just before you mount a shelf - do the following: Instructions say to put 2 screws in each expandable rail end (remember the first step mentioned above). And you did to get this far. Now that you have extra screws available, go add 2 more screws to each end of the expandable rail, and another set in between the now 4 screws you have on the expandable rails at each end(these you set to determine the depth of the 4 post open rack on the first step in the instructions). When you get done with adding these screws you will have 6 at each end of each rail - so 12 per expandable rail X 4 = 48 screws just in these expandable rails. Why? It adds a lot of strength and tightens the whole unit up nicely! No you won't get anymore weight, but you will see the difference. Overall I can't complain about this 4 post rack. This is NOT something you would use to mount up 3K+ UPS's, servers, storage, etc into. I mean, look at the price! There's a reason enterprise data center racks for business start at around $2k each and up. This isn't the same thing so expect what you paid for, not something for on the cheap. Anyone who's worked in IT, would immediately see the difference here. But for home use with up to 2x 1500 UPS in the bottom with home grade equipment racked up, it fits the job just fine! Slap a Monitor/Keyboard/Mouse on top and you're ready to go! I've already got some extra shelves coming along with some patch cables in the right length to tidy up everything on a single rack that roles when I need it to. Oh, and don't forget the 19" PDU so you can reduce down the wiring nightmare that some of us get into! :) Stop thinking about it and just order it! If you need something more heavy duty then spend the money and move along, cause that is a different class of need than trying to make this work for the real heavy stuff. Good luck!

Awesome.. Had it on me basement for Karaoke System Management. Nice fit Polk Audio PSW125 SUbwoofer....ongoing NOTE : Subs on Floor not attached to the rack Sorry for the mess hey :)
