So this the rough draft design of what I am calling the Queso case (you know because chili Queso is the best!)... The case will be laser cut out of .177" (4.5m) acrylic and easily glued together.

120mm fan mounts to the side and blows air over the mosfets, you can run it in multiple directions based on what's best for your cooler (thank you GrapeApe for suggesting that it be able to be turned horizontal for big air coolers). And easy access to all the cables.

The plan is that the back-plate will have 2mm of foam (cut out in the same shape as the plate it self to act as a bit of cushion.

I've got to make 10 of these for myself, but once I figure out the effort, laser time & material costs involved I'd be happy to cut some out for others and flat-pack ship them to ya.

Once I have a working prototype I'll snap some pics and have a better of idea of what it cost of others one some.

Can they be screwed together or must they be glued?
How many Chilis can an enclosure hold?

They look good Hands!! Definitely get in touch with me when you finalize design and cost. I like em...

Yeah that was a good quick inexpensive find and perfect timing for me. On another note the prototype that Hands is making looks great I got a look at it earlier today and it seems like it should be a good alternative.

You might win the auction yesterday as I did. :-) I won three more and already have two so total 5 chilis from Monday. All of backplates, collers, and chilis will arrive Monday!!

I just ordered the last 4.

Edit: It says there are more now.

Do you mean the last 4 of the backplate I uploaded? Actually, it also said last 4 when I first purchase them. They may have much more than that.

Yep, but 4 is all I needed thx for the heads up. Also thx for posting the find. Are they nice and rigid, no board flex?

Welcome!! The plate is really thick, almost 2mm. 2mm steel is enough strong to protect pcb from bending.

Man, I love those mosfet heatsinks... I got some of these

http://www.amazon.com/gp/product/B00CJRZP9I/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

they are rather dinky :-(.... I think I am going to order those too and return the ones I got..

I did snag 5 of these (2 cards per PSU)
(
http://www.newegg.com/Product/Product.aspx?Item=N82E16817438016

Single rail so I don't have to worry about which rail is serving power... ( I suppose dual rail is better if you know that one PCI-E plug is on one rail and the other is on the other.. but no way for a layman to really know that).

Building my own back plate and holder setup... Once the prototype is done I'll share the details :-).

My cooling solution!!

1. Backplate: http://www.amazon.com/gp/product/B004W8AOK2/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
http://ecx.images-amazon.com/images/I/312-Z8M8bZL.jpg
The black rubber looks like shadow. It is rubber sheet for insulation. The steel backplate is very thick and sturdy.

2. Cooler: http://www.amazon.com/gp/product/B005SEZBXY/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
http://ecx.images-amazon.com/images/I/41Un70yxiNL.jpg
This horizontal cooler may be good to chill down MOSFETs.

3. MOSFET Heatsink: http://www.amazon.com/gp/product/B004CLDIHK/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
http://ecx.images-amazon.com/images/I/41py58WVcGL._SY300_.jpg
3M thermal tape is included.

4. Raspberry Pi
No need to describe

No need to buy additional screws. I could attach both of the backplate and the cooler just with screws provided by Cooler Master.

I put all these in my garage, and for the internet connection, installed a WiFi multi-bridge, which transparently connects the Raspberry Pi in the garage to the Verizon WiFi router in the living room. My garage is crazy cold these days so my chilis show about 38GHs at below 60 Celsius degree.

So I guess Corsair doesn't think a fan plug has enough juice to run there pump and twin fans on the H80.. As such they supply one pin (fan speed?) to the fanplug and the 12v comes from the standard 4 pin plugs.

So my question is this... will our cards be ok with only getting fan-speed back without there being any load on the fan plug?

I imaging the reason they did this is they don't want to slow the pump down when the computer tries to slow the CPU fan down.. we just have a very different use case :-P

Thanks

Not having a load on the fan plug will be fine.

Frys is selling off H60 refurbs for the same price http://www.frys.com/product/7356484?site=sr:SEARCH:MAIN_RSLT_PG

I picked up a bunch of H80 refurbs as well.. Which leads me to a question I am about to post.

H60 you say?

https://bitcointalksearch.org/topic/m.3515724

Yes, and the H80's are 44.95 with a very similar attachment system.

What is the absolute best cooler for under $40?

http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099
This one works extremely well if you get longer screws to replace the standard ones for the mounting, that way you can install the backplate rightside up and it puts decent even pressure on backside of the board...giving you more even pressure across all the asic chips against the heatsink.

I have 3 of those coolers to sell, with Chili mounting kits, for 0.35 BTC each plus shipping. US buyers only please.
