PC holder that looks great and works on large PCs for easy under desk mounting
Color: Black
After a lot of research and trial and error I finally found the Heavy Duty Under Desk PC Holder. It is the only under desk PC holder that looks good and is able to hold my HP Omen 45L where I want it - under my desk. Putting it together is relatively easy as was the installation to the desk. No messing with cables or round steel tubes to get the job done. The metal is solid, the black powder coating looks great, and the installation hardware is a;l there including a drill bit, hex key, and wrench. You just need to bring a screw driver for the wood screws to attach it to your desk. Read the instructions and make sure you take the depth of your PC into account when attaching the PC holder to your desk, especially if you have a standing desk with motors.

Quality Holder
Color: White
Very quality holder and very sturdy and stable. I purchased it back in April, and it has been holding up nicely. I would definitely say that it is worth the price. I love that it's adjustable, so if I ever decide I want to new PC case, I can still use it (as long as it fits the dimensions of the holder). Putting it together and mounting it was simple. The only reason I'm giving 4 stars is that it did not come with screws, and I had to purchase some. I hope that has been changed since then.

Fantastic engineering

Awesome holder. Follow the directions. This appears to be German manufactured and very well thought out. Great having my rig off my desk - more room for my second monitor!

Pay Attention

Pretty damn good, instructions are on the right in English. Took me a hot minute to find it and was so close to getting back into Duolingo and learning German.
