7  Alternate cryptocurrencies / Mining (Altcoins) / Any interest in non-standard width "server" cases? on: October 06, 2017, 04:40:26 PM
I was wondering if there is any interest in a "server" case that is a bit wider than the 19-inch standard i.e. wider to have more room for GPUs, server PSUs, etc.?

9  Other / Off-topic / Which server PSUs would you like to mount in your 4U Rosewill case? on: August 09, 2017, 09:47:11 PM
I'm thinking about offering some adapters to allow you to mount a server PSU in a Rosewill 4U case.  

Which PSU models would you like to see supported first?

10  Alternate cryptocurrencies / Mining (Altcoins) / Gauging interest in a (to be enclosed) frame to mount 6-8 GPUs for home miner on: May 20, 2017, 04:40:27 AM
This thread is to gauge interest in a frame to mount 6 GPUs and three 120mm fans.  Enclosing the frame with some kind of sheeting is left as a DIY project for the at home miner.  

The idea is to separate the motherboard and PSU(s) from the GPUs - while still fully enclosing the GPUs for optimal cooling - for a fraction of the cost of a server case.

The frame is completely modular, which will allow the fans to be mounted at either the front or back of the frame/case.





Thoughts/comments?

12  Alternate cryptocurrencies / Mining (Altcoins) / Gauging interest in a 4U GPU mining case - Now just a drop-in bracket on: November 29, 2016, 04:50:40 AM
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?

16  Bitcoin / Hardware / Quiet server cabinets on: June 01, 2014, 12:41:42 PM
Now that the mining hardware has matured to where all of them ship in there own case, I thought it would be a good idea to offer server rack frames for mining equipment and quiet server/mining cabinets.  

Made from slotted aluminum extrusion, this unique material offers the possibility to build 3-4 layer side panels and to be very modular e.g. easily increase depth/height of the rack by simply adding "modules."  

Here is a model of a 8U frame (these could be built at any U height):





With an SP10:



All comments/suggestions are appreciated!

Thanks!

18  Bitcoin / Hardware / Multi-tier, open-air cases for Gridseed miners on: February 20, 2014, 04:42:48 AM
EDIT:  
The two-tier case is now available at GAW Miners.com.





I'm planning on building a very limited run of this two-tier case for Gridseed miners:

(This model doesn't include the miner's cooling fan.)
Model A:


Model A (left) B (right)



Miners up top, everything else in the lower tier.  

Stackable.
All anodized aluminum construction.  Positions of all of the lower beams is adjustable (to facilitate mounting all of the other HW required for these miners).  Mounting tabs for 2 PSUs.
The cases are approximately 23x20x6-inches and 12x20x11-inches (W x D x H).
Ships as a kit (un-assembled).
Shipping weight will be < 4 pounds.
The case is designed around cable management.  The power and USB cables connect to the miners in the wider areas, between rows, and then fed down into the lower tier.

Let me know if your are interested.




Here's another version for scrypt mining.  One "case" holds 20x fan-less miners.  Pictured is an example of how 3 could be stacked:

Model C:


Model A:


Model B:

19  Economy / Computer hardware / Open-air cases for ASICMiner backplane and blades on: November 26, 2013, 06:20:52 AM
For Sale - Open air cases for ASICMiner backplane and blades.

As pictured, the case is $90 (plus shipping from NH, US).  PayPal only.

The top corners of the blades are secured to the case via custom plastic brackets.

Two posts with rubber bumpers help secure the PSU.
