This is a strong and sturdy network rack. It's built like a tank, and it needs to be. I'm sure glad it's on wheels. You can supposedly mount it on the wall, but once all my gear is in it, I'm guessing it's pushing 130 pounds, which is its recommended weight limit. The rack and UPS (a Cyberpower CP1500PFCRM2U) alone are 61 and 32 pounds respectively. The 450mm depth is generally sized for network gear. Stereo gear will probably require the deeper 600mm unit.

The included fans are indeed loud, so I replaced them with two of these fans:

The fan noise is now much softer and quieter. The rack is located in a closet and you don't notice the fans running. In fact, since the rack doesn't generate a lot of heat anyways, I decided to leave the fans switched off except on very hot days.

In the rack, I have a Ubiquiti Dream Machine Pro, a Synology DS412+ NAS, a 24-port rack-mount patch panel, the rack-mount UPS, 2 ethernet switches, a nice ADJ Pow-R Bar with illuminated indicators, and a Navepoint 2U Drawer to store manuals, spare patch cables, hardware, etc. My rack is about 70% full, with room for a few more items should the need arise. Did I mention that I'm sure glad it's on wheels?

Don't assemble the side and back panels, or the front door, until you've installed all of your equipment. Trust me - you'll be moving stuff around before you're happy with it. To initially install your equipment, lay the rack on its back and drop the items in from above. This lets you visualize and determine where everything needs to go, and to place all the caged-nuts in the proper locations on the brackets. By the way, buy yourself some extra M6 caged nuts, and screws:

As for the assembly process - I'm sure glad it's over. It was a long, tedious process. Many times I would misposition something and have to take it back apart and do it again. Shelves or brackets wouldn't line up and it was because I had miscounted the bracket-holes and mounted items incorrectly. Nothing wrong with the product, and the instructions were simple enough - it was just my senior eyes not seeing what I should have been seeing. I've assembled, disassembled, and repaired automotive engines, countless kid's toys, grandkid's toys, household appliances, webstore furniture; you name it, I've probably assembled it, so I actually looked forward to assembling this rack, and I'm glad I did it; but let me warn you, this is the king of erector sets! You might want to entice some mechanically-inclined young'n to assemble this for you. No mistakes, 4 hours. Lots of mistakes, 2 days and a new vocabulary of curse words. OCD for details (my problem) - a week, with some weight-loss.

This network cabinet is just awesome! Although its sturdiness is not the best on the side panels, it is not terrible. I feel that the door does not properly close, you have to slightly lift up the door but again, I don't expect it to be perfect.

Easy to assemble - it took me around 3 hours to complete it myself. It is not horrible. If you have somebody that can help you it will be even easier but I did not find it that bad to assemble. Just carefully view all the diagrams and see where the holes are.

Fans - fans are noisy but you can easily replace them like I did.

I would definitely recommend it if you have a home lab like me!

Not sure what other reviews were talking about with the poor instructions. The instructions I got were very thorough, accurate and everything worked perfectly. Each piece of hardware is labeled in its separate bag. The unit itself is very well built - heavy metal - and all the alignments were perfect. I am very happy with this. Whatever those old reviews were talking about are no longer the case.

The one tiny downside is the fan noise. I had to turn them off and are looking for replacement units - any recommendations on a specific fan? The manufacturer said 5" in size with 4.5" screw holes, but that doesn't match normal computer fan size (140mm is the closest thing). But yeah the noise of the fans is too loud for an office or open area if the rack is sitting out and not hidden in a closet. Not a big enough negative though to deduct stars. Great quality unit at a great price.

The rack is easy to put together and is built with quality metal. The two top fans are a little noisy but not awful - I have the rack in my bedroom and they dont bother me. It's an aesthetically pleasing rack especially when used with interior LED lights. I definitely recommend!

I'm not exactly sure why so many people leaving product reviews are basing their feedback around instructions or loud fans instead of the unit as a whole. Since some people can't seem to figure it out, let me try and clarify for people looking to buy a network/server rack.

1. Yes, this unit comes disassembled, like many of the others.
2. Yes, the instructions are difficult to understand, but if you actually look at the diagrams and compare to what comes in the box, it really isn't that hard to understand what goes where. Furthermore, there's only 6 primary components to assembling this cabinet (the actual body), so if you can't get through that you should probably just pay someone else to do it for you. Maybe they can do your Legos too.
3. Yes, the fans make noise. That is what happens when air is being sucked out of a box at a rapid pace. There are fans out there that don't make as much noise, but at this price point and for their effectiveness there's really no reason to complain. Besides, the idea is to keep equipment from overheating, so that should be the primary concern.
4. Yes, it's a great unit for the price and I would have no hesitation using them again for future deployments. A 15 unit box with built in fans, locks, mounting hardware, and the ability to put on casters or use the provided wall mount that arrives in under 5 days with free Prime shipping for under $250 simply cannot be beat.

Take my opinion for what it is, an opinion, but know that it's an honest opinion of the product not the instructions.
