VEVOR 12U Open Frame Server Rack, 23''-40'' 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

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!

Some of the parts seem a little thin, but when it's all put together it's remarkably solid. The seller is also quite customer-satisfaction oriented. I ordered two of these kits. One of them had all the correct parts. But the other kit might have been a return that was repackaged because it had 2 of the same part for one of the cross bars which meant that cross bar could not be assembled. I sent the seller pictures of what I had and they sent me the correct part without an issue. I really appreciated not having to send the entire kit back and then order another one just because I was missing one part to assemble it. It's a rack, so I don't really mind if it was a return that someone changed their mind about. Their loss. It's a decent rack.In the image you can see the fully assembled unit, and the cross bar in which I had 2 of the #5 parts instead of a #5 and a #4 part. They sent me the #4 part I needed. So now I can build my second unit.Will purchase from Vevor again. Which is probably good, since suddenly I'm seeing this brand on almost everything. Hopefully they continue with this attitude of customer service. Because of my experience, I'll certainly be purchasing these products again with confidence that if something isn't right they will do the thing that actually makes sense.

This is my first server rack i have ever purchased or used. Putting it together is not as bad as i have seen many others say for the reviews of this. I did have a small problem aligning some holes during assembly but it was from over tightening screws. There is a section near the bottom that secures two 90 degree angles together but is blocked by the nut for the caster wheels.I however did not have any damage from the factory. Paint finish felt just fine but will scratch off if you aren't careful. I think the parts were shipped in a very clean manner and were all labeled what part was what, minus the screws. After i finished assembling the unit i thought it was more than sturdy for what purpose it serves.Is it going to survive being thrown off the roof? Probably not, but for its intended use it seems more than solid and only takes about an hour to setup. It did say you need two people, but i did it by myself, with some patience.The only flaw to the entire cabinet is that NONE of the adjustable parts secure together with nuts. The entire cabinet is assembled using M5 screws and you must force thread the holes with the screws. They are not self tapping either from the looks of it. It seems solid enough with the way it went together so I'm going to try and not beat this around too much so it doesn't become flimsy.I would very much so recommend that you use a drill with a Philips bit and set the clutch to a medium strength. You also have to be careful you match both sides of the adjustable racks so a part isn't installed backwards or upside down because it can very easily look like it was assembled right.To be very honest i would give this a 4.5 out of 5 only because i feel that the assembly instructions could use some improving.
