Flowkooler high flow pump 1696 for the LS2 motor has a CNC machined billet impellers are designed with an increased vane count and a reduced plate-to-impeller clearance to achieve greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps. The color is due to Type II Class II military grade anodize surface coating which protects against corrosive fluids. The pump originally had a die stamped plug plate like the OE but due to the higher pressures, we re-designed the plug and now machine a 6061 billet aluminum into a press fit plug that will never come out.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

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.

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!
