Teaser: I have my first of 4 Radeon Pro Duos arriving this week (order was split into 2 because of backlog). Planning to a "glory/dream" rig with maximum hashrate, mainly for kicks (cool factor, hello?), partly because I've done so well with my R9 290s that zi bought long ago, and because I have a good feeling about resale.

If for some reason i have a problem with one of my rigs. Well, now i can just take it out, unplug the power cable and network cable and i can put it on my desk and test
And to make those wooden frames wasn't such a big deal. Even had fun building them
HD 7870 are about £50 each so i got 4 = £200 Risers 4 (3x USB 3.0 & 1x ribbon) = £20 HP ML380 Server = £75 £5 left over for second hand cable, crimp pins and solder....
That should do 45Mh/s with 750w @ the wall.
PROOF OF CONCEPT
2 off 1000w PSUs
PSU frame out & try GPU for size
Irons out! these were for fixing TVs... way back
Put some big wires on here!
...and some on the other side like so...!
Stop for a Smoke!
.. maybe a regulator for some 5V
Hot stuff! Got POWER. Now to come off my big wires to some 16 AWG for GPUs
and back in to feed the GPU (just for now)
Well that seemed to do the trick, just need to add 3 more GPUs and more power cables and some risers.
Comments
I`m the only one who using this way the cards???
Attic?
I count around 136 gpu's over there.
Takes up a lot of space though.
Here's one part of my farm, 100 GPU's and i only need 1/4th of that space
There's an idea behind that,

POWER FIX UP
More 12v
5v Regs. one for each outboard GPU
GPU power mod so they only need one cable each
And now for a 3 card trick

This little f*cker took hours
Anyway,
TEST RUN
JOB DONE - ONE £300 WORKSTATION - 45M/hs
Full Spec Here https://forum.ethereum.org/discussion/comment/32575/#Comment_32575
Cost £60 per month to run, should find a block every 9.4 Days or 3 Blocks per month.
Plus the £300 it owes me
You planning on leaving it to solo?
plus the riser ones i found just would not fit into 6mm gap : '(
