As a real customer I'll try to be as open with this one as possible. Good stuff". Okay, that's a lot better than trying to build your own rig out of wood, screws and nails and assembling/designing everything from scratch. I only gave three stars and that's because that once assembled it actually does what it is advertised to do. Details are below. On the positive side, once assembled this rig is pretty solid and depending on your cable management skills it looks "semi" clean and professional seems to have plenty of room for cable routing and a zip tie to secure the cables to the bars.All the holes lined up correctly once I could decipher the instructions and enlarge them.The rig came with all the parts and enough screws.If I was going to try To build one of these myself, using tools, wood and my time, I would probably invest a lot more than just buying this rig. And because it's aluminum, it's stronger than "bi lliges" wood with the same diameter. On the 8 GPU model with the included brackets, you can use 6x140mm fans for the quietest possible operation and more airflow. (Note: my model had multiple fan brackets instead of separate fan rails.) There is actually a product website for this, so go here to download the instruction PDF for your purchased rig (6 or 8 GPU) to view on your computer screen or by you print larger copies. All in all it could take 3 to 4 hours as I got frustrated and kept going for 2 days and got back to it. The included instructions are unusable because the print is too small. They are also opaque so you don't know exactly which part to assemble in the correct order so you might end up going back a few times like I did. I had to go online and download a PDF copy and even after printing my own I had to zoom in on the real PDF to see some detail. Even then I had to "invent" some things myself. If you plan on installing two or more of these, there are no specific installation instructions for that, so good luck with that. You decide what is best for you. The instructions show how to mount the bar to the front of the rig while supporting the front of the GPU. However, you may want to mount the bar toward the back of the rig so PCI Express adapters can be installed on it. This increases the GPU performance a little more than what is shown in the images. If you are using the "mini" versions of the various GPUs, you will need to install a bar on the back. Since I had mine already assembled when I saw this (and my cards are full length), I might leave them on for now, but will likely replace them later if I need to remove the rig for maintenance. The PCI Express risers seemed secure enough to stay in place without sitting on the support bar, simply using their own locking mechanism and slot tension. It's probably best to install the bar further back in the setup and ignore the instructions/drawings on how to do this. The fan mounts are awful and add even more build time. The one I bought had multiple brackets that require the fans to support each other when all fans are installed instead of a single mounting rail. A splint seems to be a more durable choice. However, with separate mounts, fans are never 100% fully rigid, especially toward the center of the fan array. The fan screws are "thin" threaded, so they can have a tendency to "pull" if you overtighten. I've noticed that fans with front-to-back screw holes are less prone to screw breakage. And why are the fan brackets neon blue and yellow? Why not use white, gray or even just black for fasteners? The supplied screws for attaching the mainboard and graphics card to the rear mounting rail are below average at best. These are hex head screws and the heads are quite small and when tightened they almost go through the graphics card bracket and motherboard mounting holes. I've decided to use real (thin thread) computer screws that usually hold the CD or motherboard in the computer case for a better fixation. The included screws will work if you don't have anything else, but that's about it. Here the technique seemed to me to be a little better. Relying on corner supports for the floor, horizontal support beams seemed cheap but worked. These angled mounts were very difficult to install and align properly. But I think the overall cost was the main issue. The obvious: No, the rig doesn't come with fans, but why would anyone think that? The picture also shows graphics cards, a motherboard and power supplies, but they aren't there either. Photos should show how everything looks after installation. Use your common sense guys!
