Gauging interest in a 4U GPU mining case - Now just a drop-in bracket

[Spotswood]

I'm thinking about offering a simple 4U GPU server case for the DIY miner.  The case will have the "standard?" ability to mount the GPUs in either orientation and spacing, have an inner support wall for fans, designed to rest on a 1U shelf, and ship pretty much bare bones (no fans, grills, etc., bare aluminum).

Hoping to sell this in the $300-350 range (shipping from New Hampshire, USA).

Thoughts?

Tip: Not enough place for PSU and MoBo in this layout

Heh?

for bare aluminium price is just way to high. Anyway i don't see in your design hole for cables that connect motherboard and raisers. Only option is one fan hole but then only 2 fans...

I dont see why anyone would be willing to pay 2x GPU money. I built my frames for 20$ and never had a problem.

Gray Matter has shown there is a healthy viable market for GPU chassis like this. Not sure why the haters are the first to drop in on your thread. Good luck with the project.

Change the GPU Orientation to face the opposite side, so that blower style Cards can be used too. Also, if you have onboard video disabled it would be easier to access the GPU HDMI port if they are turned the other way.
But there is a market for these, I am trying to make them myself because of sourcing issues.

Heh?

You need to have width < 19", so in your current layout you can't use 2 PSUs, E-ATX MoBos... And as i see, power cables from PSU need to be longer than a standart ones...

So I would be interested but the price......

I made one for myself similar (almost exactly) like padrino buying a 4U from newegg and making the modifications. I cost me less than 100$ to do so, not sure why people are charging 3x the price. If the price could be dropped...

(not sure the manufacturing costs)

I think people would be interested.

I mentioned in the OP that the GPUs can be mounted in either orientation.  They can also be positioned anywhere along the depth of the case.

Yes, this design can only accommodate one PSU and ATX-size motherboards.  The current depth of the case is 26-inches, and shortening it wouldn't be a big problem.  The GPUs can be mounted in any orientation and positioned anywhere along the depth of the case.

No one will pay for this frame that money, so yeah you can only wish 300$ price.

i see a slight problem with this case... why are you blowing hot air from the gpus onto the motherboard/psu/ram/ssd/cpu... etc etc?

Its a fairly standard layout, but I suppose you could put the MB and PSU at the front?

For what it's worth, I would recommend against using 80/20 (or whichever extrusion you're using) for a 4U build - you're much better off just repurposing an existing 4U case, as the cost will be substantially less, as will the weight.  Design some sort of inserts that would go into an existing case in order to make it correct for mining - as there are many existing 4U cases that have tons of mounting holes already in them.

I love 80/20, and I use it for all my builds, and it's great for prototyping but it will kill your margin...  Oh, and the design as shown won't work because of the sheering force on the front mount, you'd want to mount the ears onto your side with something like these:

This way the force of case is loaded onto your top and bottom beams.

BTW; I love some of your builds - your IKEA drawer one is brilliant!

The picture looks dang! Nice drawing but the price is horrible. What about 60 to 80$ price?

[louie2001912]

I would pay $100 tops for a case like this. I've made one before with the Rosewill 4U case for $69

[Tmdz]

$300 is just crazy, for that money most everyone will build their own for a fraction of that.

you guys have really no clue how much these kind of solutions costs (prototypes, components, logistics, human work, adapters, instruments, working tools, drills, etc, etc)

60 bucks?

Yeah, build it for yourselves. Good luck with that
