There is a serious lack of rig porn on this forum! I just spent a few hours getting one of my stubborn R9 290 cards up and running. Ended up having to make a custom BIOS for it to get it to stop crashing the drivers or whole computer, but at least this rig is back to 5 cards! Will move it back to the mining building tomorrow if it stays stable.
5x Sapphire R9 290 Reference Cards
ASRock H81 Pro BTC Motherboard
USB risers
2x PSU (Antec 1300W Plat and Corsair HX850 Gold)
Some 2x1s, cheap metal racks, glue and screws
138MH/s total
Total cost... I don't remember, they've paid themselves off several times tho!
Let's see your rig! Nothing too shameful to post - those 6 card rigs haphazardly arranged on your desk are just as good =p.

I might suggest having something the cards sit on as well to have a normal force balancing it!
This is my basement rig. I'll take pictures of my two sets of 6x R7 370 gpu systems tomorrow as people are sleeping.
This here are two pcs. One with
PC 1) GTX 690 watercooled. Check out my custom loop in there with awesome XSPC radiators, reservoirs, and EK waterblock.
32-35 MH/s
PC 2) HD 7990 + R7 370
55-60 MH/s
I know it's super ugly, but it's really convenient and cheap! I wanted these ones open and easily accessible. The ones I have upstairs are built in wood frames that cost about $5 per rig.
These two systems cost me about $900 canadian to buy over time and these 2 produce about $700-$800 / month. and have paid for themselves a few times over now.
The 6x R7 370 rigs cost $1300 and that has paid itself over a few times now too.
Though I'm from Manitoba Canada and power here is 7.6 cents / kWh (5.8 cents USD)
They ran mounted like that for over a year before, so I don't think it'll be an issue anytime soon (I built these rigs when litecoin GPU mining was still profitable). Given how annoying those plates are to remove, I think it's pretty solid. Yes, mounting them vertically like that drops the temperature A LOT. Those cards stay under 60degrees C with 60% fan speed. Mounted horizontally, 100% fan speed didn't keep them that cool. The distance between cards was also fairly optimized. Any closer together and the middle cards started to run hotter.
LOVE that "ghetto rig." Reminds me of when I setup a 6x MSI R9 290 rig splayed all over my living room table. Left it running like that for 2 weeks before I built a decent frame for it. Damn those cards were crap tho, reference cards were honestly better, so I sold off the MSIs eventually.
In BC myself, so power isn't quite as cheap as you, but close (7.97cents/kWh until 1,350 kWh, then 11.95cents/kWh).
Really good to know it won't buckle the metal part on the cards. I'm going to do that right away!!! Never thought of that and am so glad to see someone done that. never even see that before!! LOL i'm so happy
MORE PICTURES GUYS!! I'm dying to see more pics and had a hard on when @work started this thread haha.
Will have it filled before the end of this month. First rig ever and it is going okay!
1 GPU is missing at the top and 1 at the bottom that will have 6.
If people put a lot of time and money into their mountinng solutions, it'd defeat the purpose ROI.
@ditto don't forget to have some cooling!
I also first bought a cheap $40 plastic rack, then decided after reading some horror stories to go out and buy this one for $90.
Ran out of power and now having to pay a electrician to install a breaker for each PSU. A couple miners are spread across my house while these are in the cold basement.
Here's my DIY Rig with 8x Tahiti Gpu's (7950-280x) ~160Mhs total.
Check out the power switch!
It's made from a £3 wooden shoe rack.
one cooler master runs 3 cards and + xfx runs 1 card+mobo,cpu,ssd on both side of the rig.
3.8kw is a bit overkill, but i want them to run cool&quiet with good efficiency
6 r9 nanos
8gb ram
intel 3.8ghz dual core i3 processor
asrock h97 anniversary mobo
120gb ssd
Great setups peeps
you can just align the bottom of the cards and the risers with the rack rails
>half of those rigs are ziptied cards on walmart/homedepot style carts, but I LOVE it!
It might be time for me to make a multi-shelf arrangement as well.
Some ppl here have >100 Nanos
One of the few people with vertically mounted cards, and those ones would probably be better off horizontal.
