Up for offers is a completely custom, one-of-a-kind, nothing exists like it on the market, graphics card (GPU) mining enclosure/barebone system.
I built these three years ago to run 25 RX-480 blower style cards spread across four 4U enclosures. So a set of 2 4U enclosures have 13 high quality PCI-e risers with 1x master risers and 16x mechanical slave slots, powered by 6-pin PCI-e 14 gauge wires to independent power supplies.
Each 4U enclosure has a custom made dock for QTY 4x HP 1200W server-grade 1U PSUs (INCLUDED), providing a maximum power delivery capacity of 4800W per 4U enclosure. You can power any gpu on the market in these enclosures.
Each 4U enclosure is powered by a single molex 4-pin male power connection on the back that triggers all 4 12V PSUs and two very powerful 120mm intake fans to power on. The fans are strong enough that there is plenty of passthrough air through any blower-style card. If you use a non-blower style card, you can use less cards with some slow spacing to exhaust the heat.
When I ran these with 25 total RX-480s installed spread over the 4x 4U compute boxes, the cards ran with temps in the mid 50s to mid 60s throughout their lifespan, in an AC-cooled server room kept at 68F/20C ambient temp.
This sale includes QTY 4x 4U compute boxes, with risers (source and destination), high quality USB 3.0 6ft long connection cables, 4x HP 1200W power supplies (per chassis, so 16 total included), fans, and rails to mount these in your own rackmount cabinet.These boxes also have variable power speed adjustment knobs added to the front to control the fan speed for noise/fan RPM control.
You simply cannot buy anything like this on the market and I developed these for my own use. I needed a short-depth (approx 20" deep) chassis setup to fit in my server rack that let met me control and exhaust the heat from the cards in a uniform fashion, and these absolutely delivered.
I'm exiting the mining business so I'm looking to pass these onto the next blockchain enthusiast!
The price reflects the hardware included, and the countless hours of work that went into modifying the cases and setting everything up to work.
