Let me start by saying that I do like the quality of most of the materials, and overall it is a nice bench, but there are a few things that really bothered me with this. My Biggest issue is the radiator mount. Upon mounting the radiator in the bracket and installing it on the bench, the block of an AIO will not reach the CPU and that alone makes this product useless to me. I also have some qualms with how the PSU can only be mounted on the left side/HDD can only be mounted on the right side which is the opposite of the orientation of the SATA ports/power plugs on your motherboard. The instruction booklet says, "These brackets are modular and can be oriented on either side" except the mounting holes on the left and right side are not spaced the same. The material quality overall is great, but the nylon screws are junk. Finally, my instruction booklet has some serious printing issues. I had to find a pdf of the booklet and print my own.
The bottom line - I gave it two stars instead of one solely because I like how sturdy the bench is, but design flaws cripple it's functionality. And after spending $300+ on a product, that is simply unacceptable.
