101  Other / Off-topic / Re: Which server PSUs would you like to mount in your 4U Rosewill case? on: September 13, 2017, 01:50:23 AM
Prototype mount for DPS2000BB PSU leverages the 80mm fans for cooling and mounting.   Cool







There is ~65mm between where the motherboard would be and the bottom of the mount.

Comments?

Added Rosewill Server Chassis, Server Case, Rackmount Case for Bitcoin Mining; 4U Metal Rack Mount Bitcoin Miner for 6 GPU; Solution for Building a Mining Rig (RSV-L4000B) to the list of supported cases.

This is a less expensive version of the RSV-L4000 with out all of the drive cages that you have to remove anyway in order to install my support bracket.

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?

I have verified that the bracket fits perfectly in a Rosewill 4U Server Chassis / Server Case / Rackmount Case, Metal Rack Mount Computer Case with 8 Bays & 7 Fans Pre-Installed (RSV-L4000), which is currently listed on Amazon for $90(!) less than the RSV-L4500.

Shown in the pics is an optional bracket that the IO assembly can be mounted to (via double-sided tape).

I've verified that 38mm thick fans will mount to the frame (via some extra black plastic fan tabs). 

Here's a video: http://www.spotswoodcomputercases.com/images/VID_20170728_160118.mp4


How much to get the fan tabs? Or any way I can do them myself? What fans that fit in the front is the best airflow output?

Getting 70/70/59/70 Celsius on my 4 x 1070 (3 hottest are blower style) when i close the front With the key. Leaving it open i have 67/66/51/64, but server will be moved to a facilty requiring to be secured.

12x tabs will all required fasteners is $15.  However, you can get away with just using two tabs to mount the two outer fans, thus 8x tabs is $11.

I would recommend getting blazing fast 25mm thick fans, or switching to 38mm thick fans (which are the size used in the video).

You should also experiment with removing the filter material that is in the door, to see if that reduces temps significantly.

Hey Rich,

Any update on when you might be shipping out another batch?  Placed order on the 20th and starting to get impatient already.   Grin

Currently have 10x in stock.   Shocked

density is key to keep investment low and maximize roi, this boards are a god send. for now, we need some new stackers to accomodate the setup
Ehem.   See post #102  Roll Eyes

With the optional GPU tier, is the two PSU version frame still stackable? If yes, I think I need to buy an extra connector for stacking, right?

Yes, everything is stackable and all hardware required for stacking is now included, standard.   Grin

Rich, will you soon take new orders for the Drop-in bracket for Rosewill RSV-L4500 ?

I am taking orders now, but please note the price increase in the OP.
114  Economy / Computer hardware / Re: [FS] All aluminum open-air case frames (new option for 12/13 GPU boards) on: July 06, 2017, 06:13:22 AM
Any updates about the 12 GPU frame for Biostar TB250-BTC Pro ?

New optional GPU-only tier for our two PSU mining tray:



This option along with a dual PSU tray is the perfect frame for the  Biostar TB250-BTC PRO or ASrock H110 Pro BTC+ motherboards.







$95 (for the optional GPU-tier).  PayPal only.  Shipping from Washington, US.

In order to mount 12/13 GPUs, along with the rest of a rig, also requires purchasing a standard dual PSU tray.

Here's a first pass at a design for an open air frame for these boards:






Hi Rich, I'm interested in this open frame, when will you be able to produce it?
I will be adding this to my "for sale" thread (https://bitcointalk.org/index.php?topic=1487782.0) next week.
116  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASrock H110 Pro BTC+ 13 GPU Board on: June 28, 2017, 08:31:39 PM
You could use a single PSU for this board e.g. http://www.parallelminer.com/product/2400-watt-power-supply-kit-for-gpu-mining-94-efficiency-200-240v-ethereum-eth-zec-dash/

I think it should fit 7. Just did one and was able to install 6x Gigabyte GTX 1060s with fairly good amount of space between them.
Both short version RSV-R4000 and long version - RSV-L4500, RSV-L4000 would work (short case better for a shorter single fan cards)
Longer version is better since it has more space inside to fit another layer of case fans.
You just need to disassemble front drive bays and DIY fit cards facing forward, might need to reverse fans depending on GPUs (some like exhausting to the back, some like EVGA GTX 1060s exhaust the other way)
You can see 7 slots for GPUs in this pic: https://www.google.com/search?q=rosewill+mining+case&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjyjJDR_cfUAhUMxYMKHfvGAXQQ_AUICygC&biw=1920&bih=977#imgrc=G51yTJo5MQ3D5M:

119  Alternate cryptocurrencies / Mining (Altcoins) / Re: Gauging interest in a (to be enclosed) frame to mount 6 GPUs for the home miner on: June 09, 2017, 04:45:28 PM
I'm interested in this.  When can we buy?
The response to this idea has been lukewarm, at best.  Which I don't understand, since (albeit if sheeting were applied) this would be an alternate to having to buy (and then modify) a server chassis.

Is the inability to mount the motherboard and PSUs to this frame is what is lacking in this idea?  Or, simply the lack of sheeting?





120  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASrock H110 Pro BTC+ 13 GPU Board on: June 03, 2017, 06:16:40 AM
I'm looking forward to building a frame for this board.   Cool
