Kingwin 8 GPU Miner Rig Case Frame – 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.

Best Rig I have ever assembled. Quality material. Amazing design everything flows, everything was built with airflow and heat disipation in mind. I just wish the instructions were a little bit better. Maybe with a little bit of text but still 5 out of 5 for me. Will get more and would highly recommend to everyone.

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.

I modified this rack to hold 2 motherboards whilebspacing apart many GPUs.

It arrived quick, the instructions were lacking but not really necessary. There are only like 6 pieces to assemble and it's fairly straight forward and quick. It comes with a driver for easily tightening the standoffs into the frame. All in all, it's a great purchase for a 6 gpu rig.

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.

This case is very badly designed * Long cards do not fit, if you're planning to put backside fans, e.g. 3080ti gigabyte! * There is no weight support for short cards, I don't know why they put supporting leg so far away, 23cm from the front, e.g. length of zotac 3060 is 21.5cm, so it does not reach the leg. * Only one point of connection between pair of side legs and the main frame, it holds on one screw and friction!! You'll understand what I'm talking about during first steps of assembly * Only two points of connection for PSU, could easily made 3! * Poorly written manual, some steps and accessories are missing * Overpriced, for this price I'd not expect to spend so much time for assembling and then modding to make it work for my cards.

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.

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!?).

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.

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.

I just built a 12x RTX 3070 rig with this frame. This rack is larger than all other that are sold on amazon, so you can put 5x 120mm fan on the width instead of 4x 120mm fan, this space is much needed to have some room between all GPU. All those 4x 120mm fan width rack that are available on amazon are not wode enough for BIG gpu with big coolers. I have an asus rog strix beside an evga ftw3 and there is plenty of room between those 2 bulky gpu. The overall quality of this rack is awesome, I'm not scared to move it arround, it is really solid and well crafted. Here are my only complains: - This rack assume that you are using ATX PSU. I have Server PSU, so there is nothing to help me to fix those perfectly. I was able to tie-wrap them on the rack but it doesnt look "clean". Maybe they could put a bottom that is full instead of being open and put some spot where we can attach some tie wrap, it would be way cleaner. But this "issue" is something that is on every rack sold... -The depth of the rack could be an inch more. It fit perfectly for all my GPU except for my ASUS ROG STRIX that are longer than the other. To make it fit I had to force/bend the bar where I screw the GPU so that the GPU would fit, and the other side of the GPU is forced into the 120mm fan. Fortunately, it doesn't force against the blade of the case fan but only against the casing of the case fan, so it doesnt prevent the fan to spin. But an extra inch to allow us to install those long GPU would be nice. - It is promoted as being able to stack multiple rack together, but nothing is included to attach them together. I'll have to 3D print something to be able to fix them solidely when stacking them as I dont want to just let it sit on top of each other. -Price is really high (150$) compared to all other 12 GPU rack available on amazon (less than 50$). Yes there is approx 4.75"(120mm) more in width on this one, but 3 time the price is a little greedy. The only reasons why this isn't a 5/5 stars is because of those little flaws.

Thoughtfully designed, had no complaints or no complications on my custom made open rig
