Kingwin Miner Rig Case Frame 12 GPU – Premium Stackable Aluminum Mining Rig Enclosure for Efficient Crypto Mining, Test Bench PC Case.

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.

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.

Kind of annoying to build and work with, but for the price can't complain. Setup a sweet 6 GPU setup with two power supplies using this, works fine. It does come with a CPU power switch you can use as well.

It goes together much like an old-school Erector Set model. I've not assembled a case made of extruded aluminum before, nor have much experience with these specific materials, but -- to be fair -- I built a RepRap from parts I printed myself, and ... if it isn't obvious based on the purchase of this case, I am completely comfortable with assembling a PC from parts and have been doing so since the early 90s.So, assuming you're a computer builder and want an open air, well built case -- this works.I do not have the number of graphics cards that this case is designed for (I top out at 3), and chose to buy this case in hopes that I could re-purpose anything that was left. For the most part, I did. I kept the top row off, entirely and my PC runs cool.As for quirks: the aluminum bar that the PCI-E cards screw in to included two holes for mounting the cards (they assume you're mounting graphics cards that take two slots). In the kit I received, the left, but not the right of these holes was threaded, the other was not and was too small to accept the provided screws. The screws were weaker than the aluminum, so forcing them in just stripped the threads. I had similar sized screws that were a little more durable which were left over from my 3D printer build, and they were able to tap and grip.I'm *very* please with the build-quality over-all. The extra $10 for the upper section was left off, entirely and re-purposed to replace part of the franken-enclosure I have for my 3D printer.It came with more screws than needed to accommodate everything (even removing the upper section). It was sparse on other common case parts -- it came with a switch, but no LEDs or other things typical on cases (I expected this and didn't want any of that stuff, but if you're looking for that, you'll need to buy them separately). It comes with no fans (also desired -- fans included with cases are usually loud/cheap) and -- as would probably be expected -- it comes with none of the required wiring for hooking the fans to controllers (or adapters to get them powered). So plan on getting all of the necessary cooling parts (it comes with a power switch).Packaging was excellent, there were no scratches/damage to the unit.Thankfully, as well, the manual that it ships with was available online.

In my opinion this is one of the best mining frames for the price. It’s very sturdy and the instructions are easy to follow. To those complaining that it cannot house larger GPUS , you can message the sellers and they will send out an extension bracket that works perfectly . I have 7 3080 ti’s and fit without issues.I pair the rig with the 4300 rpm fans and it works perfectly . Would definitely be purchasing more of these for my future rigs.

Package arrived in great shape. Unboxing was smooth, had to be assembled but, at first glance it was only 20 or so pieces. I thought I'd knock it out in no time. But that was not to be. At first it all seems straight forward. then it's time to attach the legs to the bottom frame... there's these great L shaped plastic pieces that have to be screwed into the frame. Only, there's no screw holes. Instead there's a channel the runs the length of the piece and you have to insert wide V shaped metal bolts into the channels and then screw into them. Seems simple enough except...they turn... and when they turn, there just small enough to come completely out of the channel. There's obviously an art to this type of fastener that eludes me. After 30 or 40 attempts though, my skill has improved. Instead of 20 mins per leg, at the end it only took me 10. Which brings me to another point. I never thought I'd muse wistfully at the clarity of IKEA instructions. Oh, how I'd have loved some IKEA instructions, or old radio shake instructions. You know, "insert tab A into slot B while holding G and Q and bouncing on a beach ball." And there was plenty of that sort of limber floor gymnastics going on. Like juggling while playing twister but to be fair that could be because of my lack of general coordination. Needless to say the instructions have decent diagrams...and that's about it. In the end, it's all together, I'll knock out inserting the computer hardware sometime tomorrow. All that said, it's sturdy, it'll do the job and it only took 3 hours.
