Kingwin Miner Rig Case Aluminum W/6 or 8 GPU Mining Stackable Frame Expert Crypto Mining Rack for Ethereum Classic, Flux, Ergo, Neoxa, Ravencoin–Improve GPU Air Flow Cryptocurrency, Test Bench PC Case

Very easy and sturdy to build. A little fiddly on the edges but nothing a little patience won't fix. Ended up being quite fast to build to. Note that the fans and risers are not included (I knew that but forgot to order the fans when ordering the frame!?).

I bought another brand of the same design for my first build but this was less than half of that one's cost. I am not going to defend the instructions that come with it, they're awful. To anyone who complains that the holes don't line up for a motherboard, that is because if you follow exactly what the drawings say, the bottom part is backwards. Just flip the bottom part over before attaching the sides. The bars that hold the fans are super sturdy and I prefer this over that little plastic pieces of the more expensive brand. Yes, it does take some time to put together, but it's not very difficult. Just remember, the pictures show the bottom backwards and you'll do just fine.

CONS: You need to pay attention how to assemble it and not 100% follow the instructions as the bars holding the GPU risers are not in the correct way on the images, some mistakes on labeled screws on the plan, etc. If you use logic, you will be able to assemble it in under an hour. PROS: Nice looking mining rig, I went from regular 6 GPU mining frame to wire rack from HomeDepot to this Kingwin 12 GPU, what an upgrade! The rig is solid, looks very nice and best cooling also (with good fans of course, Noctua). I highly recommend this frame to anyone, not cheap but kinda worth it right now.

The 2020 aluminum extrusion are very well made and it's black anodized. Screws holes are aligned well. It took me less than 30 min to install. Very sturdy and light weight. Only issue I had was my ATX Micro motherboard did not have good mounting. This RIG may have been designed for full size ATX motherboard but I did not see this written in the description. In any case, my motherboard had enough mounting to be stable. Be aware for the height of the bottom shelf, I have a Cooler Master AMD Wraith Ripper CPU cooler. This so tall, the top exceeds to the upper shelf. Be aware of this height. This is my fault not the design. I should have picked a smaller CPU cooler but this one looks so cool and priced very well.

Frame came with all necessary components. Loved the dedicated frame for FAN Also came with extension joint rods got for stacking. Great purchase. Note: there are minor typo errors on instruction manual. But common sense works well.
