4 out of 5 eggsGreat mini-rack

Pros: STURDY- this thing can hold a LOT of weight and the overall "fit and finish" of the rack really impresses me, especially for the price. Love the option of wheels or leveling feet. I'm only using the wheels which roll pretty well even on carpet. Included SOME bolts and cage nuts (see Cons)

Cons: Very heavy, although it's not wasted weight as the unit is every bit as sturdy as it is heavy. Supposedly can't use rails with this, but I generally prefer shelves for support anyway. Also, as others have said, more nuts and bolts would be nice.

Only issue I've had has been the bottom rack space. Due the weld at the bottom of the vertical supports sticks out about 1/4 inch causing anything in the bottom 1U to sit too high and/or misalign the holes. So until I used a file and dremel to clean up the welds, I basically had a 14 and 1/2 U rack.

Other Thoughts: This rack is holding a 4U file server loaded with HDDs, a PDU, a rack shelf, a couple of rack drawers and a bitcoin miner. Perfect for a home work or project station.

1 out of 5 eggs1 star for the product and 1 star for newegg

Pros: None as we could not assemble product.

Cons: Product arrived missing assembly hardware. Contacted Newegg and they let us down. First they checked their warehouse for missing parts, couldn't find them. Then they offered us $25 credit and instructed us to buy the hardware from the manufacturer. The manufacturer doesn't answer the phone. We are a 50K a year customer and this is how they treat us. Created my own RMA for replacement, tried to contact Newegg about shipping label. They won't respond

Other Thoughts: Newegg's customer service has taken a massive dive. Considering shifting my business to other vendor.

4 out of 5 eggsDecent rack

Pros: Sturdy construction, seems like it will hold my gear just fine.
Good price range.

Cons: Disappointed in the packaging. It arrived very scuffed up in 4 places because the feet were not secure in the box, and must have moved quite a bit during shipping. Not too big of a deal. though as 2 of those places get covered and the other 2 areas I have facing the wall.

Also very disappointing that it is 15U but only comes with the hardware to fill one-half to one-third of those slots with 1U gear. It really wouldn't cost much to throw in 20 more nuts and bolts... that would earn it a 5 star rating from me.

Other Thoughts: A simple black and white set up guide printed on one sheet of paper would have reduced the set up time by 1 or 2 minutes. Would be nice...

4 out of 5 eggsSolid Simple Rack

Pros: Solid construction.
Quick to assemble despite lack of any instructions.
Fit my components (non railed components) just fine.
Wheels are good quality (as are the leveling pads though i didn't opt to use them)

Looks nice overall... not as nice as a rack cabinet, but still pretty cool and impressive looking for a home setup.

Cons: No manual. It's not particularly hard to figure out how to put together... but a simple 1 sheet diagram really couldn't hurt. Check out James C's review below for the link to some excellent pics that assist if you are unfamiliar with rack hardware.

No extras of critical screws. While there were exactly enough screws to put everything together, there were no extras of these components... not a huge con, but including at least 1 extra of each critical piece couldn't possibly cost too much extra.

Scuffed/scratched in places. The scuffs were eventually removable with magic eraser, but the underlying scratches and a few other small ones on the corners of pieces are an annoying cosmetic defect.

As others have mentioned the screw holes for attaching the posts to the wheel bracers are hard to get started due to them being slightly painted over. Not a huge issue, only had any difficulty on one of the holes that really seemed to require more force than it ought to, in order to get it started. As some others have mentioned, once you get them going though, it is fine.

Extremely minor issue is that the spots where the wheels are attached stick out more than they ought to IMO. I can see where putting them in a little more toward center would obstruct attaching the posts properly, but there has to have been a way to accomplish both without the wheels jutting out in front/behind the rest of the thing quite so far.

Other Thoughts: Despite the much larger con section, they are all extremely minor, and I still would highly recommend purchasing this if you need a somewhat budget rack for a small business/home.

4 out of 5 eggsGreat Rack

Pros: This is a great little rack; very solid and adjustable for small spaces. Other reviewers complained about it not accommodating all widths and depths, but really, if you use the recommended shelves, then you can go as deep as you like regardless of how far apart the verticals are (reverse the dog ears on the shelves, so the extend OUT along the shelves rather than inward).

Cons: Net well suited for railed servers, according to other reviewers. I've not yet encountered that problem.

5 out of 5 eggsI love this and will buy another

Pros: It is super strong steal. capable of holding a 1u mini case with out side or back support. If you are not using super long cases you can move the racking mounts closer together for shorter servers. The holes take standard screw's and nuts from any old racks. The wheels are of great quility and can stand up to all the weight.

Cons: Not sure this is really a con but it's heavy. I'm not sure if it's just my case but there isnt room for side rails, I had to use back shelves

Other Thoughts: I have two heavy steel 4u's fully loaded with 5 harddrives each and 2 1u's. I needed to buy a back support shelf due to the weight of the 4u's but still got the two servers within one bolt of each other. I wish it had a mount for a power strip at the bottom, but since it moves on wheels I can see how that would cause an enegeering issue.

5 out of 5 eggsworks great

Pros: This rack is strong, sturdy, equipment fits great, rolls easily on carpet and doesn't need instructions to put together. If you need instructions, then you shouldn't be in the business.

Cons: High shipping costs, but that is because it is heavy.

5 out of 5 eggsAwesome - Under- rated

Pros: STRONG (I'm using over 100 lb UPS units, yes, multiple)
STURDY (on castors, OR large screw feet with rubber)
EASY ASSEMBLY (Seriously, no instructions needed**)
DURABLE, nice and even finish and coat.

Cons: ***(Barely even a con, but someone else complained)
If you're mounting the castors, the holes are not pretapped/prethreaded. It requires simply screwing the screws in with more force. (EASY, TRUST ME) I did this with my Hitachi powered screwdriver. Not even wrist strain.
They're self tapping screws, people, jeez.

Other Thoughts: Alright. I was very reluctant to try this rack out because of its previous negative readings (2/5 ?) but it turns out, this is SPECTACULAR.

There's a little room for improvement, but this unit is GORGEOUS. Any other cons are me just nitpicking and being a prick.

1 out of 5 eggsCompletly useless...Even with their server cases/mounting hardware. STAY AWAY!

Pros: Feels sturdy, looks decent.

Cons: Does not fit either of the 3 Norco cases that I had. Like other reviewers have stated, it is slightly off. I even purchased their mounting hardware to go with this rack (which wasn't cheap). I own two Norco RPC-4020 4U and a RPC-4224. None of their cases would fit with their hardware/mounts. Unacceptable. Their support seems to not care enough to check their dimensions of their hardware they have in their stock to make sure its correct. I sent them several emails with pictures of my hardware requesting basic information (that they should have on their site) and they refused to check. They wanted me to purchase more expensive mounts they assured me would work (they said the same thing for the 1st mounting brackets I purchased). Norco shouldn't be making server racks if they can't stick to standards or even support their own server cases. I also had a hard time assembling it all because of the extra layer of pain on all the threads for the screws.

Other Thoughts: If you don't need to screw down your equipment (or put them on anything but the bottom row, than this could work for you. Otherwise stay clear or this rack. Its a shame they wont listen to our reviews and own up to their mistakes. I spent over 8 hours trying to get it to work (I tried everything) and got nowhere. I really wanted it to work as I didn't want to pay to ship it back. After dumping several hundred dollars on the rack/mounting equipment and spending countless hours with their mediocre support (by email only) to only have a rack I can't use was very upsetting. Norco makes good server cases, server racks...not so much.
