This is why I was thinking of doing a 5U case. That will allow me to raise the cards a bit off from the mobo and space them apart so intake fans don't get blocked. Then all the cards can just be hooked up with ribbon risers.

Anyway, looking at all these other designs has given me a lot of ideas to test out and luckily I've got a lot of time this weekend to get some more work done on designing.

Yeah that looks really simplistic. I could take that design and cut it out on sheets of acrylic no problem. Heck, I could do that sell them for a similar price, but I don't think it'd be worth doing because the profit margins just wouldn't be there. I don' t want to start out with an open case design though, I'd rather do closed.


Yeah a friend had linked that to me. I had the plan for doing something like that for a couple months, but looks like he beat me to it. For such a basic stacking case design, he's really asking for a lot of money. $245? Are you kidding me? I'll be able to get the prototype of my case done really cheaply and when I'm ready to sell I can definitely beat that price.


Interesting you said that. I was actually planning on doing a 19" 5U rackcase. I was thinking about 4U, but I wanted to make sure it was tall enough to fit 2 PSU's and some of the taller cards. Do you have any design tips on doing a rack case?

I posted this in the newbie section since I wasn't able to post here, but it got instantly buried. Now I've got access to the important areas so now I would like to talk to you all about an idea that I plan on fabricating. I am planning on building a custom case designed for housing multiple video cards while providing enough space in between intake fans so they are not blocked. I've got access to a lot of cool and expensive equipment for constructing this case. I can design something in a CAD program and then get it cut out for me and piece it together.  I’d like to get as many suggestions and ideas from the community as possible while in the planning stages. I hope to complete a prototype of this case within four weeks or less. If everything works out, I’d like to begin selling these cases as well at reasonable prices.

Here’s a list of some of the equipment I have available:

 
Epilog Legend 36EXT Laser System - 36" x 24 – Used for etching or cutting certain materials like acrylic

Epilog Helix 24 Laser System – 24” x 18” – Same thing just smaller

Shopbot CNC Router – 4’ x 8’ Can be used for cutting metal (This is what I’ll mainly be using for cutting stainless steel, aluminum, etc.)

Dimension 1200es Series 3D Printer – Prints ABS plastic with dissolvable supports for parts with overhangs (Might be useful)

There is also some other equipment too such a cornstarch 3d printer and some smaller tabletop CNC mills, lathes, etc.

Right now I'm designing it in AutoCAD. I'm thinking about making it a rack style case that's open to allow easy access to adding cards. I might have removable panels along the sides and top too so it can be closed if desired.

So, please offer any insight or ideas you might have. If you have any questions, I’ll try my best to answer them. If you guys have any other design ideas that you think would be cool for bitcoin mining feel free to tell me about them.

I'll be sure to donate a small amount to help you out.

Probably around $20 dollars now, but it'll gradually increase as time goes on and bitcoins become harder to mine.

Cool, I'll have to check this out later when I have time.

I like the milk crate idea. It's cheap, effective, and easy to transport.

I think the 5850 has the most bang for your buck.

Oh and if a mod could move this thread into another section that would be great.

The 5850 has a very minor overclock of 800Mhz on the GPU clock, but I've done this with the default clocks too and I'm still having the same problem.

I'm not using crossfire, PSU is 650 Watt and it's Corsair if anyone is curious, but wattage isn't an issue here. Lastly, with both cards mining simultaneously and the memory clocks at 900Mhz they are running at 69-70C each.

Lately I've been trying to lower the memory clock on one of my cards and every time I try my entire system locks up and I have to restart.

I'm mining with 2 cards, a 5850 Xtreme and a 5830 Xtreme, both from Sapphire. If I just lower the memory clocks to 900Mhz in the CCC everything works smoothly. So, I was looking around on the forums about how to lower the memory clock beyond that. I found a thread advising people to try using MSI Afterburner to get the clock all the way down to 300Mhz. The problem is after I open MSI Afterburner and select the 5850 and try to lower the memory clock below 900Mhz, after about 10 seconds my entire system halts and I have to reboot. Catalyst seems to get a little fussy after this too and I've noticed that when I try to plug in my second monitor my computer will eventually halt again. I fixed that problem by completely removing catalyst and doing a fresh install, but then that leaves me back to square 1. Does anyone know how to fix this issue?

Oh and if it matters I'm using the 11.5 Catalyst drivers on Windows 7 x64.
