Title: self made mining rig from switzerland
Post by: ovski on July 02, 2017, 12:48:46 PM
Hello Everyone

About half a year ago a friend of mine and I started to build a mining rig to setup a little mining farm. Currently we got about 12 rigs up and running and are pretty happy about it. Shortly after we setup everything, a neighbor has seen our farm and asked if we could build him two of those casings, and so we did.

Just for fun we built some more and put them on an online market platform like e-bay here in Switzerland, and in a very short time we had sold around 50 of those casings.

Currently we got some of them left, so my friend asked me to put a thread up here on bitcointalk to find out if there are people on here that are interested in such a product.
We also would like to know what you would expect from such a product and if there are any features that are currently missing that we should try to introduce.

Here I'll link some pictures of the current release:

The casing is made from aluminium and is including metric m3 screws with a hex key head. You'll need a 2.5mm hex key. (https://en.wikipedia.org/wiki/Hex_key)

Features:
  • Up to 8 GPUs (We mostly build the 6 GPU version but we also have it running as 8 GPU in our own farm)
  • 6 riser including special 3d printed insulators
  • 3 x 140mm fan with grill and speed control built into the casing
  • Screws included for 6 GPUs (again we can increase this to 8 GPUs if you like)

The price for the 6 GPU version is 690 Swiss Francs or about 720 USD, there currently is no price for the 8 GPU version (shipping not included)

So please, if you have any questions or suggestions fell free to answer this thread or send me a PM.
Currently we don't have many casings left so I'm not putting up a sell thread but if you are interested in buying a casing please send me a pm and we can try to sort things out.

Thank you

Fyi,

Gray matter make these cases for 550USD inc risers so i would re-check your pricing.

Way, way overpriced compared to flex design: https://bitcointalk.org/index.php?topic=1921659

This doesn't include the fans, grills and risers but even then it's a much better value proposition.

I see your point... I don't know how he can work at this price level. Probably doesn't take him very long to build one of these casings. We'll have a hard time getting anywhere close to this price  :-\

We got standard open frames in good quality (aluminium) including pre-screwed holes, screws and spacers in Switzerland incl. 6 Risers for less than CHF 300,-- so i think you should think about your calculation again.
A closed frame just raises the noise level as you need faster fans to get out the heat from such a small box.

I believe the majority of miners use an open air frame since it tends to help with the heat issue quite abit. Your cases look nice, they just might not have as big of a market as an open frame design would have (at least for mining rigs).

... but I guess these cases might be better to mine in datacenters.

It looks beautiful. You should have gone for open panels though.
How much hashrate are you getting?

yes, we now realised we are totally off the price range. We have to recalculate and see if we still want to do this at the given prices.

As for the closed design, we have to prove you wrong. This design is sucking air through the casing and is working very well. There is a tower of 9 casings running inside a closed wooden frame. At the backend of this frame is a industrial fan attached sucking the hot air out of the room. If someone is interested I could put some pictures only of this setup.

With this setup your heat is not spreading, you can control where the heat is going and deal with it.

We didn't want to go with threads in the aluminium so we used threaded rivets. This way we can easily fix damaged threads if a customer would hit a screw to hard.

Thank you   :D
What panels do you mean? The sides of the casing? Well we went for closed design on purpose.

Total hashrate? hm... hard to tell as they are not all going for the same coins. But calculated it should be around 2.1GH/s for ethash. But that is clearly a wild guess ;)
