So me and a friend have access to a tempcontrolled room where a buddy of ours runs his tech company.
He's willing to let us put a rig in there if we compensate him for electricity.
So now we're trying to figure out how to best approach this whole thing. Since we're both cheap, we're obviously trying to not go all-out on all the components. The rig will run Windows so us noobs kann remote-access it. There will be no overklocking or somesuch shenanigans.
I'd like to present you with our choices so far:Mainboard:
Gigabyte GA-890FXA-UD7 link in German
, but you will get the details, if you wish.
6xPCIE (2x16 2x8 2x4)
Thing is - we don't know if this thing could take 6 dual slot design GPUs... if you should have any idea of such a motherboard, pray, tell!
Some cheap AMD thing
4 Gig of somethingorother
We consider a 16GB stick, or just some cheap HDD
Now here's where it gets interesting.
With 6 slots, we'd obviously run into some kind of temperature problem when trying to run 6x the highest-end card there is.
We're currently considering
6x 6870 which runs at ~150€ per piece.
The thing is, we don't know if 6 of these monsters would fit in there. If there's only room / technical provisions for four cards, dammit, that would suck. We should get 240MHash/s per card, so it would make quite a difference if there's 4 or 6 in there.
Additionally, we're unsure about the power supply. Which power pack would you advise? Would standard cooling procedures suffice, or is there need for additional measures?
I also came across this
open case, which looks awesome.
Hope someone will comment on these first ideas - thank you if you do!
