Reducing the gap between the backing plate and the impeller
Pontiac owners have reported that (1) heat cycling may result in a distortion the backing plate and (2) coolant degradation may corrode the backing plate necessitating replacement. Some aftermarket plates may have a deeper dome and incremental cooling gains may be experienced by reducing the backing plate-to-impeller vane clearance. In closing the impeller-to-plate gap pressure is built, efficiency is achieved and more coolant will route to the thermostat and radiator which initiates the engine cooling process. Please note that inadequate clearance that results in an impeller vane to backing plate interference will cause friction. Owner modifications to the Pontiac part design are performed at the owner's discretion and FAILURE TO MAINTAIN ADEQUATE CLEARANCE WILL VOID WARRANTY.

Great solution
Color: White
It’s embarrassing to say that I love this thing. Nothing falls out, it’s completely hidden, I’m so glad I didn’t go with one of those attachable C shaped wire basket things. It’s absolutely perfect.
We have a motorized sit stand desk.

Amazing. A bit of a job to set it up but worth it!
Color: Black, Color: Black
Excellent quality. Sturdy and strong. The screws that come with it are awful. Get yourself some different ones.
Takes a while to set it up and get it all measured. I did it while I was setting up my new Flexi-spot E7 Plus standing desk. Wanted to get it all done at the same time. At first. I thought it might be overkill, but I am sooooo glad I did get this. Now my computer moves along with the desk. It looks great. I bet it has improved the air flow around my computer as well.
Looks sleek and cool.
I might have set it a bit too tight around my case and as a result I have to shimmy it to get it out of the holder if I have to do any work on the computers internals. But at least I know it's secure. My suggestion would be to leave a little bit of slack to avoid this in your setup. Maybe like a 1/4 inch would be ok. The pads should hold it in place anyway. May loosen mine up if I find the time.
But it feels totally secure on the desk with no wobble or shaking.
Great product.
Also I'm a woman in my late fifties 😃and I was able to set it all up on my own. So don't be intimidated ladies, you can do it too.
I also bought two of the ultimate set up cable management trays. Great products.
Note for anyone from the Ultimate Setup company who might read this. Please provide better quality wood screws and some extra ones) I stripped three of the cheap ones that came with this. And it took forever to drill them in because they weren't strong enough. Then it would be perfect.

Awesome quality
Color: White, Color: White
Take your time installing! It comes with all the instructions and templates. Make sure you’re screwing this into solid wood. I would not recommend you hang your expensive PC from a particle board table.
My Pc fits in well and it’s compatible with a ton of different sizes. Mine has been mounted under my desk for about 6 months and is rock solid. I will say, mine is balancing in there. If I don’t have it at its center of gravity, it could tip out. You can adjust it with the various screw holes but make sure you mount it into something solid.
