Garage / Residential Data Center Mining Cave Planning - Garage Grotto Part 1 :D

[VoskCoin]

Hi guys I decided to make my own thread as I have a lot of questions . .

First I'm looking to setup an in home mining cave, I only have funds for ~5 rigs currently but I have goals of filling rigs to reach my electric capacity (200 amp box)

http://imgur.com/a/kUQqI

Please review my pictures, garage is semi underground, area is all cleared out now for mining, however a car will also be stored in the garage, it is a 1 car garage but honestly about the size of a 2 car garage.

You can see the panel in the back left, I am planning to upgrade the electric

Question #1 Can you please explain the rough max electric I can run for this system and how I should do it?

Question #2 How can I manage heat in this setup, there is only one door to the exterior which mimics a front door and then the garage door, the area closest to the concept mining area which is that indent in the garage however it does not have to be there, just seems to make most sense?

Question #3 Racks etc, my setup will be mostly GPU rigs, whats the best rack setup I can use as far as being useful, cooling, and looking decent

I have more questions but these are my main concerns at the moment, would love all input on how to successfully create this so that the setup is very efficient.

Looking it over.

Okay you have an interior door  where does it lead to?

My idea is build a diy barn door inside the garage mount one fan like this


http://www.homedepot.com/p/Ventamatic-Cool-Attic-1650-CFM-Energy-Efficient-Power-Gable-Mount-Attic-Vent-CX2500UPS/202913826

so if you open the interior garage door  you see the diy sliding barn door  and there would be a fan like above pulling air into the garage.  obvious you need screens

the fan pull air in could be this one but must be at the bottom of the  interior entrance.

this will bring in cool air from the house.

you will need an exhaust fan

which means put a window in the garage to exhaust air out

Interior door leads to the basement hallway connected to my bedroom one way and stairs the other

Also side note, I want to consolidate this into one thread and philipma I know we've talked briefly about this

I have a rig consisting of this

5x Sapphire Radeon VAPOR-X R9 280X 3GB GDDR5 w/ boost pcie /// ZCASH 1300h/s not overclocked

Intel Core I3-4160 Processor 3.60 GHz, 2-Core LGA1150 Socket, Hyper-Threading

ASRock H81 Pro BTC Mining LGA1150 HDMI SATA 6Gb/s USB 3.0 ATX Board

2x Seasonic X-850(SS-850KM3 Active PFC F3) 850W 80 Plus Gold ATX12V/EPS12V Power Supply

2x Crucial Ballistix Sport 4GB Single DDR3 1600 MT/s (PC3-12800) CL9 @1.5V UDIMM 240-Pin Memory Module

Kingston Digital 120GB SSDNow V300 SATA 3 2.5 (7mm height) Solid State Drive (SV300S37A/120G)

Power Supply Reset Switch Motherboard Cable

5x PCI-E Express 1X to 16X Riser Adapter USB 60cm Cable w/ SATA or Molex Powered

KADA 6.1 GPU Mining Rig Open Air Frame Case Aluminium Chassis

Dual triple power supply adapter connector Relay Adapter link multiple add2PSU

I have a spare powered riser, no spare cards, and can add another card onto the PSU w/ 2 cards --- so really I am just trying to figure out how I can add a 6th card to this rig (running windows 10 w/ trixx) I do not want to sell the cards I think I'd rather just add 1 more, with that in mind should I hunt down another 280x? What about a nice nvidia to continue zcash? or Simply an rx470 4gb and turn this into an ETH rig

[Sequoia93]

#1. You said you had a 200 amp panel, is that a panel dedicate for the rigs, or your whole house? If it's a dedicated panel for rigs, then its simply 200*240*0.8 = 38,400 watts, or half that for 120v.

#2. You are gunna need an intake/outtake. Garage door is the obvious intake, using louvers. There are many examples around the forums. Definitely check out @yun9999's thread. I would turn the door to the outside (i don't see it in the pictures, but I believe you said one exists) into an exhaust. This would be easiest if it is a door you never have to use. You could mount a large fan in the top half of the doorway. What you'll need for fan size will be determined by how many rigs you have, and the ambient temp. Do you live in a hot area or no? That indented area may be fine for the time being. If you scaled enough I may worry that it is not close enough to the exhaust (although, again, i don't see the door, so i'm not sure). With 5 rigs i'm sure its fine.

3. The best racks for looks are definitely 42U server cabinets, but you'll pay up for them for sure. Metal wire shelving units that many miners use are much more cost effective, but are ugly and cable management can be difficult. I've also been told the server cabinets are better for cooling, I can't say from experience, but it would make sense to me.

Phil, feel free to correct me on anything

Interior door leads to the basement hallway connected to my bedroom one way and stairs the other

I put info above.  I think you can feed cooler air in via that door.

but you need a window for an exhaust vet in the garage.

cool air in basement >>> garage door >>>>> miners >>>> exhaust vent

So here is my base layout of the garage, if that is the case I would have to run miners right next to that door in order for that airflow concept to be efficient? What do you think based off that floor plan?

Phil, feel free to correct me on anything  

its for the whole house, so I'm thinking I could cut it in half to dedicate to mining?

Thanks for the input please review this http://imgur.com/Nij8gSv

I live in a relatively hot and relatively humid area (virginia) and I pay 14c kwh so I need the setup to be efficient as my electric is not cheap

https://www.newegg.com/Product/Product.aspx?Item=N82E16816228172&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Server+Racks%2FCabinets-_-N82E16816228172&gclid=Cj0KEQjwrsDIBRDX3JCunOrr_YYBEiQAifH1Fl9raOwfOqCvS1kjQYIZ308iBLQgzYc9LdZVj1TX0i0aArSs8P8HAQ&gclsrc=aw.ds I would never profit a dime with racks this expensive! lol I'll definitely opt for the metal wire shelves xD

[Sequoia93]

Yeah if you're lucky you can find the server racks used for cheap, but I still opt for wire shelves. Home Depot and Wal-Mart sell similar brands for cheap with a 600lb rating per shelf. You could fit ten rigs on this: http://www.homedepot.com/p/HDX-48-in-W-x-72-in-H-x-18-in-D-Decorative-Wire-Chrome-Finish-Commercial-Shelving-Unit-6T60184872C/100655787

For the electric, I would opt to add a 100amp (or two 50amp) circuits into your box at 240v. Or maybe swap some 120v circuits for 240v if the box does not have the room. It will be pretty cheap to have done since your box is in the garage and the electrician won't have to run wires a long distance/through walls. The 240v circuit will help with efficiency/your high-ish electric rate. I'd talk to @Finksy about some platinum server PSUs if you plan to have 5+rigs. Again, it'll help cut the hurt of the $0.14 electric.

As for cooling, I'd personally put the rigs right in front of the door going to the outside. Exhaust fan on the door, you might be able to put a louver in place of the window on the door. Then I'd put louvers along the bottom of the garage door for intakes. Just make sure you have enough to match the power of your exhaust fan. If you do get up to ten rigs, I'd get a fan ~3,000CFM, but that's a serious shot in the dark. idk nvidia rigs, and idk virginia.

[Marvell1]

start with 200 amp or you will regret it in the long run

[VoskCoin]

start with 200 amp or you will regret it in the long run

I can only run half at most I'd imagine with my house box being 200?

[gwestcot]

I would definitely have a dedicated panel installed just for your mining. You will more than likely want to expand and you want to have the circuits and the amperage to do it.

[navydude]

I just did a quick read through the posts and could have missed something. I would use exhaust fans as recommended but I would separate the mining room from the house. Do not draw the air from inside the house, pull the air from outside. Arrange the rigs so that the air pulls directly across the rigs. You want a exhaust fan big enough to exchange the air in the room several times per minute. Even if the temps are 100f outside, when you are pulling that air across your 65c to 70c card temps they will stay cool. 70c is 158f so the outside air will cool if you have proper air flow. 3000cfm is a good starting point. I am moving my rigs out to a 12x26 storage unit that I had set in the back yard. I am going to go with 7,500 to 10,000 cfm because i want the air to be exchanged many times to keep the heat minimized. There is no reason to put in a 200 amp panel right now unless you have the money and know you will add several more rigs in the future. Its gonna cost so be prepared.

I have 9 rigs on my main 200 amp panel. I dedicated 4 double pole 240v breakers just for mining. You dont want the breaker to be loaded more than 80 percent. If you run your rigs on 240v you can double the amperage of a 120v circuit and run more efficiently. At 240v you could run approx 20+ rigs on a 200 amp panel. The wire racks work perfectly. It gives very good air flow for the cards. Unless you are rolling in the money there is no reason to buy those expensive sever racks. 75 bucks will allow you to set up 6 to 8 rigs on a nice wire rack. Thats my 2 cents.


I was actually thinking of this. Haven't decided on fan size yet.

[Sequoia93]

OP, if you take a picture of the inside of your panel, I can check how much room it has to add circuits. If it is full, you may need to add a second box, but it really is not that expensive.

this is my idea for him he needs to cut 1 vent in back corner of his garage.
he needs a strong exhaust fan so air is pulled from cooler home.  
this setup keeps gear away from car and lets a car be parked.
only one cut in garage for vent.
and cooler air flows into garage from basement
if ac bill goes too high  he can close basement door  and open garage door 2 inches use this

from garage door to vent  inside door shut

http://imgur.com/a/kUQqI Please review the album as I have uploaded 4 more pictures that show the layout a bit better and also show the panel

Apologize for all of the junk everywhere, still moving myself in and have some of my familys stuff stored here as well for the next week

What could I potentially cut down  to maximize my potential energy, looks like I could squeeze ~25 rigs onto 100 amps?

Granted I don't have 25 rigs yet but that is most certainly the goal!

I'm really willing to go to any extent to make this happen, but budget is certainly a concern! http://imgur.com/a/kUQqI please review the updated pics for a little bit of a better idea, I will also upload a picture of what is in the area behind the extended portion of the garage, it is essentially a small maybe 6x6 utility room with my water heater / ducts

I appreciate your concern for the car xD as I am a car guy and will have to park my racecar in there however my focus is on the mining rigs as the car seems to spend a lot more money than it makes lol

I am willing to put the mining gear anywhere along the basement door side / the "cubby" area / basically anywhere but the footprint of a vehicle in front of the garage door + the wall on that side is pure concrete

Does that number seem accurate? ~25 rigs max based on my power capabilities? so we should be building cooling based on that? Also what is "too hot" for a miner to run are cards running at 80c+ "too hot" what exactly is an ideal temp, okay temp, bad temp, and critical temp?

How would I effectively move the air? I could understand cutting a portion out to install an intake fan and blowing the air across the rigs if they were stationed next to the basement door
review pics below
http://imgur.com/a/kUQqI
I'm worried even that space left there next to the door may not be big enough? I could figure out a way to replace the door with a large fan . . I have two entry doors and could simply enter exit through the true large garage door or the other entrance door. This might actually be one of the better routes as there is already that large hole there simply filled with a door? What are everyones thoughts?

My goal is to make an efficient and cost effective setup to handle as many rigs as I can. Once I have acquired funds/ setup max rigs (currently only have ~5 rigs worth / most are parts en route etc) I'll have 2 GPU rigs running by the end of the week and the goal is 10 GPU rigs by the end of july / 5 by the end of the month)

Also for example one of my mining rigs is the mining cave cheetah https://miningcave.com/product/mc-cheetah-sk1/ it's running on standard 120v socket currently, with these atx psu (this uses rosewill 1200w (photon/gold)) I simply plug into 220v correct? How do I ensure units are setup to handle increased power as to never damage a unit

Certainly not rolling in money and I'm thinking the metal wire shelves will be perfect for my setup goals and above all ..  budget!

[VoskCoin]

I would definitely have a dedicated panel installed just for your mining. You will more than likely want to expand and you want to have the circuits and the amperage to do it.

If my main panel is 200 amp is there any chance my system could potentially have the capacity for a 300 amp panel and they simply put a 200 amp in or do they always put the max amp box per your electric setup

I won't comment on the air flow thing because I haven't looked at that too much. I wouldn't buy rigs from anyone since they charge such a premium and they aren't very hard to setup. I use EVGA PSU so I don't know about Rosewill but EVGA will take any voltage from 100V-240V. This would mean that you would be just fine as long as your PSU is similar to the ones I use. It will usually have the allowable voltage on the outside of the PSU or in the literature that comes with it. I also doubt that you can get 25 rigs in your garage based on the availability on your panel if you use the standard 120V.

Once I have acquired funds/ setup max rigs (currently only have ~5 rigs worth / most are parts en route etc) I'll have 2 GPU rigs running by the end of the week and the goal is 10 GPU rigs by the end of july / 5 by the end of the month)

Also for example one of my mining rigs is the mining cave cheetah https://miningcave.com/product/mc-cheetah-sk1/ it's running on standard 120v socket currently, with these atx psu (this uses rosewill 1200w (photon/gold)) I simply plug into 220v correct? How do I ensure units are setup to handle increased power as to never damage a unit

Certainly not rolling in money and I'm thinking the metal wire shelves will be perfect for my setup goals and above all ..  budget!

I won't comment on the air flow thing because I haven't looked at that too much. I wouldn't buy rigs from anyone since they charge such a premium and they aren't very hard to setup. I use EVGA PSU so I don't know about Rosewill but EVGA will take any voltage from 100V-240V. This would mean that you would be just fine as long as your PSU is similar to the ones I use. It will usually have the allowable voltage on the outside of the PSU or in the literature that comes with it. I also doubt that you can get 25 rigs in your garage based on the availability on your panel if you use the standard 120V. 

1000 watts @ 220v = ~5 amps so assuming I can fine tune rigs down a bit, and a few smaller rigs not drawing quite as much power, along with fans, I could shoot for 20 rigs?

Also sidenote for everyone participating in this thread I think I'm going to make a little plaque and hang it in the mining center to dedicate individually to each member who's helped in this thread xD


I have several electricians coming over the next week, the first being tomorrow morning actually so I can have his opinion as well as far as what he would charge to do this work. I've done a lot of work including building a freaking large tiny home lol but I did everything except for the electric & plumbing there
