Very interested in this also.

Need a case to help control the dust issues mainly.

How do you work around putting in those huge power supplies, like in the 1600W range?

That's going to be too much if you are going 1600w of heat in a case you'll have trouble.

What would be the max, like 750W?

That's more like it with a standard case, can power 3 480s and have a decent number of fans pushing out of the fan.

Open Air frame cases all the way here... My solution was to get my wife interested in mining. She's practical enough to recognize the money potential and she knew she was marrying a geek many years ago.

We now even have a rig mining next to our bed.... Kiss

I do have a full tower case for my main PC that has a pair of GTX 1080 Ti's in it (one of which mines around the clock). I would not want to put more then that in it unless you have a very large EATX tower. I tried that route back in the early days of Bitcoin mining on GPUs and it was a constant battle with heat.

I have one mining next to my bed. It has 6 R9 390, under volt and consume 1020W. Very quite.

Doable or not in a closed case?

what is this "brake pedal" you speak of?

I would be curious to see how a case like the Thermaltake Supressor would do in regards to noise reduction. If you had 3 blower style GPUs with a space between them, and good quality case fans, I think the cooling aspect would be good. You would probably want to leave the front door open for best airflow. It's a reasonable price ($95) for a full atx tower with sound reduction built in.

my nxzt h2 is a "silent" case, also with a front door and sound deadening panels.

they do reduce sound but not by much. please dont think they will solve all your noise problems.

The roswill server case with drop in bracket keeps 6 cool for around $160.

Are you referring to the Rosewill RSV-L4500?
What is the drop in bracket mentioned?

i have a single sapphire nitro r9 390 triple fan in my daily driver, its in a nzxt h2 case. 2 120 front, 1 120 bottom, dual stacked 120s rear (corsair h75 aio) and a 140 top. at night when i let the 390 go full tilt dual mining eth/dcr, the card is fine at 65% fan at 65*C but the case fans ramp something crazy. very noisy.only run it full tilt at night. daytime i set the powerlimit at -40% so its pretty quiet,

figure one 300 watt 390 is about the same at 2 470s or 480s. have fun.

For a while I had 1 MSI Armor 480 4g and 2x Visiontek 470 4gbs reference cards in an Enthroo Pro full tower case. I had the Armor on top and the 2 visions below. Ambient temp was about 70-73 F. Cards sat about 75C with fans around 70%. 1 200 in the front as intake, the fan that came with it. 1 rosewill 120 Fan on the HDD bay inside to push air. 1 140 on the back as exhaust, fan that came with it, and 2x Corsair 140 AF series on top for exhaust. My HDD bays are completely full as well, 5x HDD's and 1 SSD. It kept decently cool for everything I had in there, but the noise from those fans was so bad.

My rig runs 4 EVGA hybrid 1080s in Corsair Air 540. At full load the cards run at 60~70C.
The case is designed for airflow. I also use a fan controller to balance between noise/cooling. It (white color) looks decent too.

If you want to build 4 way sli, definitely go water cooling/hybrid. The cards will sit extremely tight together. If you go air cooling they'll choke.

Good to know the hybrid works so well. Just burned one of my two 1070 in a mid atx case. I know the upper one is hotter than the bottom one (~73 vs 60 degrees), but though that's still in a reasonable range.

aka ...

It is a little hard to find a case with 8 PCI-Slots,
but it is working

2 x 120mm fans in front and bottom work fine
with 2 x RX470 + 2 x RX480, even in summer

Yeah I have and am doing so again. What I had was 5 750ti in one tower. No issues, now I'm doing 480/470 mix with Max 4 cards (most likely 3) and putting lots of fans in them. The wife would freak over my beast of hanging cards or my giant server.

750ti was pretty low power draw, less than even a 470 iirc. larger cards will overheat a case more.

I have 2x 480 (8gb) in a corsair spec-01 case, and even at slight undervolting and TDP limiting, the case gets quite warm and they sit around 70C with 60% fans. If they were open-air, theyd probably be at 60C with 40% fans

distribute...

i have a pc in each rooms (upstairs). a pc downstairs and a pc for surveillance...all are with a GPU or two (all are mining).

putting them in cases and letting them standing next to each other is useless, they are better off without cases

setup servers(different kinds), computerize/tech up your home and put GPUs in them to mine...by distributing them around you distribute the heat..

this is where the bigger and badder GPU's have an advantage, take ZEC for example, 2x 1080 ti setup can give you 1400 sols.

note: the more GPU you can put at each PC the better.

tip: do you have a problem in specific areas where humidity is a bit high? where mold and mildew grows?...put a mining rig in that area Wink

I think cooling will be your biggest issue. Make sure that you invest in some good fans like Noctura. Also, look online on how to manage airflow in your PC. I had to rearrange wires to promote better airflow in my PC.

the haf-xb is the best, or the corsair air 540 https://bitcointalksearch.org/topic/cooler-master-haf-xb-361613

I did the haf and it really wasn't, iean you are essentially making a half hanging rig and they are still tight and blowing on each other. (That and the damn thing is massive.)

are you sure i can't see how it's different than a open frame, they look very similar, i have now an open frame with the same space between the gpu and all my gpu are at 70° maximum(70% tdp) with 26° ambient temperature
