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.

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.

This is a great rack for the money. I was hesitant to purchase this at first because other reviews mentioned: incorrect instructions/confusing, a lot of assembly time, difficult assembly, and flimsy construction. Here are my thoughts on each:Incorrect Instructions:I found an error on page 4. I included a photo of the correction attached to this review,A lot of assembly time:I didn’t think it was too bad. It took me about two hours. I highly recommend and electric screw driver/drillDifficult assembly:Honestly, I feared the worst from the self-tapping screws. However, I was surprised that they actually worked quite well. I only stripped one screw and that was probably my fault. I highly recommend using a screwdriver extension for the hard-to-reach screws.Flimsy construction:Overall, the rack is pretty sturdy and great for light loads. I would probably not fill it full of HP Proliants, though. The wheels do not seem super sturdy, but they have not caused me yet.Overall, great rack for the money.
