I purchased this mount to acquire more desk space on top my desk.I had looked at and read a lot of reviews from other cpu mounts. I'd noticed this one had a more sturdy look to it and all the reviews I read were very good. After I received the mount,I installed it easily ( follow the simple instructions ). This mount firmly holds the computer. You can move the computer forward or backward, and whatever position you leave your computer the mount sort of lock or tightly holds the computer in a stationary position. The computer fits tightly inside the mount bracket and it does not swivel or lean. It's pretty neat ....and it looks cool. Highly recommend !! !!!!!!!

So, I have a GeekDesk Max and this fits perfectly under the desk so regardless of the height of my desk, the computer is out of the way and rises up and down with the desk. It's very easy to install and holds my computer securely. I love that it swivels and slides back and forth so that it's easy to plug cables in and turn on and off.

I really wanted a five-star product. But here is the issue. I have a 9" wide by 19" tall desktop PC. The flange that goes underneath the computer only extends 5 1/2". This means there is tremendous pressure on the dust filter and metal mesh on the bottom of my PC when I would prefer that this flange extend the full 9 inches. Second, in order to get the PC into the unit, I had to either take off its rear foot or give the whole PC another inch of space to hang down. It was quite a pain. Third, the plastic arm that drops down to hold the the PC in place against the flange coming down on the other side only contacts the PC near the top. No contact at all any further down. It looks bad and looks precarious. Fourth, it would be very helpful when mounting my PC in the unit to remove the plastic holding arm. But you cannot do this and reassemble it with the PC in place. But this seems to be an oversight because parts are all machined to accept a 5 1/2 long bolt that could fit into the knob currently attached to a 5/8" or so bolt. The longer bolt would allow you to put the plastic holding arm in place after placing the PC on the metal flanges. And amazing as this may seem, this being 3M, the assembly instructions were pathetic! As I messed with trying to get my PC mounted, the whole unit rolled totally out the front and fortunately, I caught it! Nothing I noticed in the instructions told me to secure it in place IMMEDIATELY lest the PC can slide out and fall to the floor. Anyway, it is all in place now. I will look into getting that 5 1/2" bolt I mentioned. I would love to extend that lower flange all the way across the base of my PC, but that may be quite difficult. Updated: The Holder as designed did not work for my desktop. It was not secure. But I got the holder to work by replacing the outer bracket with a common 15" Rubber Bungee Cord (e.g. https://www.amazon.com/ROBLOCK-Heavy-Duty-Crimped-Securing-Canvases/dp/B085Q2Z7G7/), a chain, and a third bungee hook. Why the chain vs. trying to use a 20" to 21" bungee? So you have the flexibility to choose degrees of tightness for the bungee. And mine it tight!

Not bad for the price. My computer is a bit wide and it seemed to lean a bit. Then I realized that the rack has 4 screws to release it from the rotating top so that it can be shifted to the left or right depending on the width of your computer. I shifted mine one set of holes to the right and now it sits more evenly. Still not perfectly centered but definitely more stable. I wish the holding arm on the left were metal instead of plastic.The top part of the arm is the only part that it is contact with the computer since the arm is bendable and bends out a bit when you try and get it snug. I have a fairly large/heavy computer and it feels perfectly stable in this rack. I did notice that it is best to reach back to the side-arm tightening knob when pulling or pushing the computer along the track. If you pull or push on the computer itself then this thing will wobble all over the place and I imagine is a good way to break it. They should have put a handle on it. I also installed mine further back under the desk than the instructions stated and when pulled all the way out still extends past the front of the desk by a few inches which is all I want. When pushed back fully, it leaves just enough room so that the cables are not smashed against the wall. I would suggest doing some major measuring (taking to account the depth of your computer) before installing this unless you want to be disappointed. There are rubber pads on both side, but none on the bottom.

Install was easy, I was skeptical that it would hold the weight of the tower but after my tower was put in place those worries went away. Highly recommend for quality and ease of install.

Los materiales no son de una excelente calidad pero cumple con su funcion y hasta el momento no he tenido ningun inconveniente. Si recomendaria la compra de este producto si lo que buscas es tener un poco mas de espacio, ya que al quedar sujeto del escritorio o mesa te permite rotarlo y recorrerlo de atras hacia adelante.

We have been buying these for our customers projects which hold a very large and heavy CPU. Easy to install and hold up in a hospital environment. They are cheaper here then the other place with free delivery.

I have a largish ATX case (NZXT H440 - 220mm x 513mm x 480mm). Bracket is attached to an Ikea desk with sit-stand legs and has been rather stable once I got the tower positioned so it was balanced. Seems to handle the weight and is easy to access the machine with the slide and rotate. Could have a little bit more padding and accessibility with large systems right near the limits of what fits to be great but otherwise its probably one of the best options for large and/or heavier systems.

My computer case is 17 inches high and 9 inches wide. It is a loaded Ryzen 9 3900x and therefore quite heavy. I was able to install the CPU holder under my desk with a bit of work. However, when I inserted the computer into the holder, it barely fit, was slanted and very shaky. I was not able to secure the computer in the holder. I am not comfortable with such an expensive computer being so unsecure and unstable. Therefore, I decided that I could NOT use this CPU holder. This CPU holder was the most expensive and supposedly the best built. It still did not meet my needs. I'm sure the cheaper ones would not have worked either. I will probably get a couple of wooden blocks to put under my computer to raise it a bit above the floor. This will be much cheaper and much more stable solution.
