Topic: Gauging interest in a 4U GPU mining case - Now just a drop-in bracket (Read 6099 times)

The for sale thread is up:  https://bitcointalksearch.org/topic/m.17321956

I am simply telling you that it will cost a lot more than 120 bucks. If you add fans, shipment and other details, you're in the 300/325$ range for a chassis, and for a general one. What I've shown there, in early 2014, it was a design based on a commercial product like the ones you've shown. Totally incompatible, thermally and mechanically, with yours, and customer needs.

Images speaks clearly.

I''m not sure what you are implying here, but this is just another/different solution to the same problem.

good luck with that..

80+20+20 bucks, yeah... I've spent almost 500 with tools, time, details, modding, hassle, etc, etc



Installing 300W TDP VGA's it's another thing, that 150W versions. VEGA and 1080Tis will require another kind of designs

I added a couple of posts to secure the bracket to the sides of the case.   

It's wedged into the case really well, which will make it harder to install for some, so I'm working on a revision to loosen the fit a bit and securing it to one of those holes you can see on the case side.

How did you secured frame inside the case, i don't see any screws. Doesn't it wiggle a bit?

80~$ is too much for case i believe but its good  if it is really good at cooling

Very nice. Where did you buy this case ?

@yun9999 asked me to verify that this can be re-configured to have the GPUs mounted at the front of the case.





There is 45mm between the front fan and the GPU.







Verified that this'll work with the case on its side.

  His new $50 drop in solution will make the complete server case solution more affordable and faster to deploy than anyone else on the market.  Gray Matters sells you only a Shell for $395 without even fans!  I don't believe you can buy any respectable open frame for under $50, but even then that's a different market.   Large farm needs to be efficient in space and have better control of the cool air and hot air flow.   I build my own wooden rig and even though the material is like $8-10 bucks, what's the cost in your time to cut it, etc.   I've bought many different frames, built my own, put aluminum bars in the racks, etc.  Every solution have their own pros and cons.  You can see some of my rigs evolution in the picture below from wooden rigs, to aluminum bar inside the 4ft wide rack, to Chinese open air rigs.  I also have acrylic rigs, etc.  

The final evolution is to these server cases as you can put up to 10 per 42U rack which can house up to 70 GPU per Rack in a 24" wide foot print vs 48" where I can only host about 2 more rigs in the middle.  The Chinese rigs waste even more space and can only house up to 8 rigs.  Space efficiency and better heat flow management is why people are considering these server case solutions.  However if I have to pay Gray Matter's prices, I will never even consider this route.  This is not a solution for everyone, it's more catered toward flexibility and faster deployment.  If you're doing server cases, more than likely you're not just building 1 rig so ease and speed of deployment is very important and that's why you would pay the $50 premium.  

   

If there was a case solution for less than $250 and you were doing a mass deployment for a very large facility and you could get a miner fully assembled in the server case, it actually comes out cheaper as now you aren't building the rigs at the facility which reduces the time for deployment which reduces labor cost .  Also, commercial spaces don't allow the hobbyist material of wood and pvc pipe that a lot of hobbyist use because of insurance purposes..

The GPUs are ~20mm apart.  I've been building mining frame for years.  Fingers are almost as hard as aluminum at this point.


Rosewill EATX server chassis i.e.  https://www.amazon.com/gp/product/B0091IZ1ZG/ref=od_aui_detailpages00?ie=UTF8&psc=1


The idea for a full-blown GPU server case has been abandoned.  Now focusing on the less expensive "drop-in"" frame.

Exactly, ROI is the most important thing in this business. Why should i spend 300$ for a case if i can get nice, solid and fully stackable open frame for under 50$?

What case is your 8020 subframe designed to go into?

When I built my open frames, I sourced materials for roughly $80 CAD shipped, per unit.
Definitely takes some time and the proper tools.
Be prepared for metal shavings embedded in your fingers for days.
How far apart are those GPUs spaced?
$300 USD seems a little steep, research or not, there is a limit people are willing to spend.

I didn't model the cage that goes around the fan.  The three fan "cages" are attached to the front beams.  The GPU support beam brackets are bolted to the sides of the case using existing holes (near the mid-point of the chassis).

I should have real pics tomorrow.

Can we get a visual with the GPU and Fans mounted.    Trying to visualize if the FANs are on the edge of the case and the GPU are facing the middle of the case or whether GPU will face the edge and the FANs are in the middle blowing the heat out.  How does the GPU mount to the side of the case wall?  Just via the tight fit?   Cant wait to Beta test this.

Two more improvements.

• The GPU support beam now attaches to the sides of the case.
• The front fans are support by two beams (and posts).  The beams are two pieces allowing the fans and bracket to be inserted into the case and then expanded for a tight fit.
