to be honest i prefer one rig setup than 3-4 way, with the latter would be a pain in the ass to move it, too heavy and cumbersome

Another question:
Could you please put the dimensions on the frame's rods? Did you cut them at Home Depot?
I will try to make similar - but shorter, for 6 cards only

One more question.
Do you think two threaded rods could be used to support the long bars or are they solid and won't sag?

3 cards on the way it was pre ordered :-) you can see the motherboard , psu in the corner on this pictures ;-)
It's there ;-) but not in the open case yet

nice but i do not see a shot with 16 cards and 3 mobos.

are u using win 10 or win 7 ? What AMD driver u have installed ?

make sure under control panel / power settings
Put computer to sleep : never
Turn off display : never
Let me know if it's help .

standard settings for me but it still requires that I have attached a DVI, HDMI or DP to the card otherwise the Radeon control is going nuts and also monitoring of the card is gone.
Like this :-(

How you manage that the cards are working without monitor plugged in?
I have a XFX like you but if I don't have monitor connected it gets disabled by the driver.

Now just flash them all with a 29 MHs low power mod 
Tried to flash with that modded bios , but was not able to complete the flashing process under win 10 . That mod is for reference card only , maybe im wrong :-)
You are right, mods are only for reference cards.

Lovely build rig ..can you make me one :-D
Build me one too^^ the aluframe rig

Yeah based on the pictures they are not reference cards.
I would check out the ethereum forums - mining category. Pretty sure I saw some "non reference" mods that will help.
Nice set up man nice setup

And got performance drop in an hour to normal value (like you have). Why?

Nice. Love the aluminum build, just did an aluminum angle build today. I have always wanted to try the square ones but haven't been able to find the various connectors at lowes or home depot.

So there is some information about my newest build 
My project is completed today all , 16 cards installed with custom ROM's, Take me forever to mod all those BIOSes . YEP , i have 12 XFX rx 480 , same model number , but i had to create 7 different rom for those cards to work stable. I was not able to use 1 modded bios for all 12 cards . Higher ASIC quality cards have more overclocking potential for sure , and much easier to mod those rom files for those cards:) Also i got 4 Nitro 8GB OC , those card have 3 different BIOSes . ( 13-2E3470U.X4L / 13-2E3470U.X51 / 113-2E3472U.053 ) Rom files are not interchangeable . You can flash them to another nitro , but then your hashrate will drop to lower 20's or under or just going up and down. Some of my card running over 30MH/s some is between 29.2-30MH/s STABLE !
My first priority was , creating a custom rom , with lower power draw and higher hash rate than stock .
Parts :
1.00” X 1.00” Square aluminum tubing
Local hardware store
Fiber cement siding board as a motherboard tray ( for safety reason i would not recomending any kind of wood as a mobo tray . There is a high amps running all over if something going wrong , It can be a fire hazard !!!

And the most important
16 x RX 480 card .
13 arrived , 3 its on the way
I had to shop around a little bit , bc this card had a very limited availability when i placed my orders , so i got few from amazon , ebay , newegg All cards have 8GB samsung memory , 4 x shappire nitro , 12 xfx , 1 MSI ( for my PC )

All cards have 8GB samsung memory , 4 x shappire nitro , 12 xfx , 1 MSI ( for my PC )3x 120GB SSD hard drive
After placed everything together , installed win 10 on the SSDs , before connected to internet , blocked all automatic updates , downloads , reportings , sharings ect ...used Win 10 built in group policy editor , to prevent the system crashing from some stupid forced driver update by Microsoft . Then installed Intel inf utility , then the RX 480 driver with one RX 480 connected to the mobo ! if all 6 card was connected , AMD driver installation hang during install ...
After installation completed with 1 CARD connected ,set the virtual memory to 16GB min (, turned off the pc , connected another 5 card , WIN 10 booted up , recognized all the cards ...

Fired up the bat file , the miner started hashing with 148-149MH/s , at this point it was pulling around 1100 Watts at the wall from a 120 Volts outlet . It was running stable for a few hours , then it was time to cut back that energy usage
After a little playing with wattman settings i was able to manage the energy usage down to 725-750Watts so it saved me 350 watts / mobo or 700 watts from the entire setup with 2 mobo/12cards
I let the 2 mobo with the same settings running for a few hours , it was not any stability issue , so cranked up the memory a little bit one by one under wattman settings to 2050 (8200) hash rate went up to 151-152MH/s then it pulled around 770Watts at the wall ...., both mobos running with this setting more than 24 hours without any problem .
For underclocking i reduced the gpu speed , voltage , memory voltage , target temp , power limit .
Dont want to post my settings yet , still testing the stability and will increase the mem speeds.
I was able to run my setup for 3 days with 162MH/s each mobo , with some high mem speed settings , but there was a lot of reboots , wattman reset the tune settings to factory default ... so i had to tune again one by one each 12 cards ...
was not able to sucessful underclock the miner with any other tune program , used ASUS GPU tweak , MSI afterburner..etc
wattman the only one worked for me the way i want
And there is some picrures :
