Mining Rig Frame, 6 GPU Steel Open Air Miner Mining Computer Frame Rig Case for ETH/ETC/ZEC/BTC/Bitcoin/Ethereum/Dogecoin(6GPU-V3C)

Pros:- It's a really good-looking rack- It's very sturdy- It's pretty lightweight, considering how sturdy it is.- The integrated power switch is a nice touch.Cons:- It's a bit of a pain to assemble. Take your time and pay very close attention to the details in the diagrams. The assembly instructions aren't great, but they're adequate. If I hadn't read about this in other reviews prior to purchase, I probably would have ended up putting some pieces together incorrectly and having to re-assemble them.- **No longer an issue. See edit.** The screws provided to fasten down the GPU brackets are ever so slightly too big for the notches in the brackets. I had to use more force than I was comfortable with to give them enough contact with the brackets to hold.- **No longer an issue. See edit.** The support cross beam the GPUs rest on has posts that are not made to accommodate all GPU riser boards. Granted, the risers I'm using are a bit wider than many, but even if they weren't, the support posts are offset too far from the card (yes, I did attach the support cross beam in the proper orientation - it would have been even worse otherwise). The riser boards only rest on the posts on one side, and I have to wedge something under the riser board to support the other side.- With a full-sized ATX motherboard (Zotac B150), it will still support two PSUs, but the one at the bottom of the motherboard is pushed past the PSU mounting holes in the rack. I had to zip-tie that PSU in.If you are only using one PSU, or a micro-ATX motherboard and have the specific risers (**Risers less a concern, now. See edit.**) this rack was designed for, this would probably work really well for you. I have no idea which risers to recommend, though.Edit 08/24/2021: After seeing this and other similar products in use, I realized that I did not have my GPUs mounted as intended by the product design. Rather than screwing the GPU bracket down using the notch in the bracket ear as you would when installing the GPU in a PC, you are meant to insert the screw through the hole in the middle of the bracket ear. This does offset the GPU so that it sits on the riser posts better. Unfortunately this was not mentioned in the instructions and did not initially occur to me. I'm giving this product an additional star.

Will not work with most rtx3090 as the cards are longer and require more power. The fans will be in the way, I myself made a modification so it would work. The risers they give are garbage as half of them Are bad, tried to tell them the risers are defective 3 out of 8, but they haven’t sent or tried to replace them.

PROS- Very solid and sleek construction- Quality materials- Fast shippingCONS- Instructions were very difficult to follow (pictures and text too small)- Would have liked to see more compatability for the motherboard standoff mounting holes (dosent affect operability)

1. Instructions are way too small and hard to read;2. Screw holes where GPU's are mounted are not threaded correctly for the screws they give you to use.3. Shorter GPU cards are not held up on the back end due to cross support bar being too far out. Works fine for the longer GPU's.

They do what they are made for

Instructions are terrible

Good product very happy with it.

Easy to install and works great. Now my I installed 3 GPUs, and they already reached 180 MH/s! 3 more to go
