VIVO Black 12U Freestanding Server Rack Cart, CART-SR12U | Mobile Open Frame 22 to 40 inch Adjustable Network Server Cart, Open Frame Design

Overall a nice hefty chunk of metal to mount your hobby into. I'm expecting it should be OK with a 2U PSU, we shall see. Features I like: -The metal is a good gauge, solid and sturdy, feels quality -plenty of fasteners, a few extra of each -a stamped metal wrench "tool" included -markings on the rack are clear, but not so obvious that they are garish -the fit is good, screw holes are in the right place, everything lines up, nothing was bent -the casters roll well, have descent bearings - it comes with plenty of mounting hardware for 12 units - powdercoat is good Some misses: - Hex head screws should come with washers, always - the caster nuts should be nylon or use a lock washer - it would be good if the pieces had a little label sticker A, B, C, D. Once you realize the longer end of the corner rails is down, everything can really only go together one way - packing could be better. A few minor scratches, and the box was shredded, but nothing was bent - instructions are OK, but some labeling and "this end up" would help What you will need: - A 14mm wrench (the included one will work, but it's crap) - A 10mm wrench (same comment) - A large and small Phillips screwdriver.

The assembly process was relatively straightforward, and the quality of the materials is good. In terms of "performance", I've been using this rack in my home server setup for over a year now, and it's held up well under normal use. The adjustable frame and wheeled mobile design make it easy to integrate with various network servers. I haven't encountered any major issues with cabling or hardware failures so far, as it included grounding cables. Overall, a solid option, a reasonable size, but perhaps not everyone's first choice given the price. That said, it won't be leaving it's new home in our living room any time soon.

Very sturdy. High quality rails and hardware. Instructions have small blurry images with a confusing perspective so they aren’t very useful. Individual components aren’t labeled well, or at all. Assembly can be a challenge because all 8 corners of this rack have three heavy rails that must be bolted together at a single point which is always a hassle. C-clamps and adjustable sawhorses to hold the rails in place during assembly make things easier. Pro-tip: keep all bolts loose until final assembly, install a blank or patch panel to ensure rack rails are parallel, then tighten everything up.

Solid, heavy duty materials. Sturdy rack that easily holds 600 pounds of server rack battery units. Easily moved to allow access to all sides.

Purchased the 25U model. Features: The rack is sturdy, casters that it comes with work well, labels are nicely printed, and I especially like the adjustable depth. Color: The color is a bit of a dark gray, not quite as black as it appears in the product shot and description. Compared to a couple of black StarTech shelves that I have installed, the color difference is noticeable, but I wouldn't describe it as striking. Assembly: The product was well packaged and assembled easily--about 45-60 minutes to unbox and put it together. Sizing: I debated getting the smaller 12U rack at first, but I'm glad that I picked this larger one for a home lab setup. Lots of room for storage and expansion, and easily moved around when I need to get behind it. Value: ~28% cheaper than the similar StarTech 25U open-frame. Looks to be pretty much the same, minus hardware paint differences. Minor scratches: Despite how well the rack was packaged for shipment, while I was unwrapping the pieces from their bubble wrap, I was surprised to see that there were several surface scratches in the finish, mostly indicative of a rushed prior assembly--maybe during a QA assembly, or maybe from a customer return. Either way, I decided not to send the rack back on account of these defects, as most, but not all, would not be visible when the rack was fully assembled and sending it back would be a pain. Images of nice packaging and scratched piece attached for reference. TL;DR: Overall, I'm happy with the value of the rack, and if you're looking for a rack for your home lab or small business setup, this is a good choice. Tip: As with most assembly, loosely assemble the rack--hand tight to make it square. Then when its together start wrenching the nuts and bolts down. Use a socket wrench and big screwdriver.

All the 5 star reviews are CORRECT!! 2 issues i had, which had nothing to do with the manufacturer were. 1 - shipping damage - very minor bend on one of the bottom cross member, easily tapped it straight with a small hammer 2 - When on rollers it is not perfectly level, it rocks a little bit BUT, it could have been tweaked in shipping or I may not have gotten all the casters tightened evenly - once i engage the leveling feet it should be fine. ***Pic added with names on my equipment blurred** As an IT guy i have a full rack in my garage, 42u. I needed something smaller than that but bigger then the current 12u rack AND... not $350-500 either.. This Rack is perfect, it is sturdy and heavy as heck. Assembly is pretty easy, though i used my own tools - 14mm wrench (the ratcheting kind) and a 10mm 1/4 socket so it went pretty smooth.. I read one review where someone mentioned "Lock Washers" - Yeah, definitely would have wanted lock washers, especially on the casters.. Speaking of Casters, they roll very smooth on hard wood.. Once i get all my gear in the rack i will post pics but if you are considering this - JUST DO IT! I really have nothing bad to say, i have not found anything wrong or sub-par yet... I give Credit to Fedex, dude placed it the from door (1 week early i might add) like it was nothing, i went to pick it up and woah #$%^&&*.

Easy to assemble, easy to move around with the wheels attached, the quality looks and feels great, and plenty of space to accommodate my equipment. It’s not the cheapest, but not the most expensive. Well worth its price. I’m going to repeat myself, but I cannot stress enough how easy it was to put this thing together. Just a few screws and fitting the pieces to their spots like legos. Mostly did it myself with some help holding up some parts when bringing it all together. I dread putting things like this together due to all the parts and screws, but this as minimal as could probably be. Maybe like an hour and a half to get the 25U done. Someone more handy can probably get it done quicker

This is a fantastic rack. Supremely stable and easy to assemble. The steel is thick and very stable. This rack is not light if you want to move it around youll need the wheels. Also the wheels are perfect, easy rolling and very secure as they are attached via bolt head welded directly to the frame. For the price you're not going to get a better open air rack.

Quality price it’s a 5 but I’m giving it 4 for the following reasons: 1) low quality wheels not sure I’d trust 1200lbs on them. 2) plastic side cable management 3) mid level quality rack nuts The rack itself is sturdy and well built. I didn’t need the instructions to assemble it. I’d highly recommend this rack for the quality/price ratio. If the items above could be addressed, it would an extremely fabulous rack but then it would probably cost more. Bottom line. You can’t really go wrong with it.

This is a very sturdy rack. From what I can tell, it is identical to the Startech except for the bottom frame where the casters and levelling feet attach. Steel thickness is around 2.2mm for all parts including paint (this is a hair under 13 gauge). Any sag on equipment reasonably hung from only one end is entirely from flex in the rack ears and the rackstuds I'm using. Just make sure to tighten the fasteners with a proper tool rather than the cheap stamped steel wrench included in the package, and there will be no movement once fully assembled. Packaging was excellent. Double boxed, with each piece individual wrapped. The main downside is that assembly will take some time with lots of partially tightening things and tapping with a mallet to ensure all the vertical rails are parallel with the correct spacing. This mostly comes from how the front and back pieces of the bottom frame where made; the studs the casters mount to look like they deformed the steel slightly. I may be being picky here, but this is going to matter for some users.
