Missing components, software dilemma

[vctr1337]

Gday boys,
i've been working on a rig and here are the specs so far: 4x HD7950, 8gb Corsair DDR3 1600mhz ram, Intel Celeron G3900, 8 basic cheap easily replacable fans to keep things nice and cool and 4 usb gpu risers. What i cant decide on is the PSU and motherboard. Also does the Celeron need a cpu fan too? I chose the gpus because i had one of these lying around from my old pc, the ram is from the old pc too.
Now for the software, im using nicehash miner on my main pc (GTX 970, FX8350). Im kind of new to this so i really dont know if thats a good choice.

hmph, nobody is responding, did i post in the wrong section?

 You're in the right place but don't bump your post more than once in 24 hours; that's a no no which violates board rules.
It's the weekend - people are playing at other things. Give it some time and you'll get some answers.

You could use a passiv cooler.

Go for a Asrock H97 or similiar, since you can use up to 6 GPUs.

For the PSU i would look for a 1200 Watt Gold or Platinum with 6 or 8 PCI-E 8.

yeah that sounds good, do you know if there is a cheaper gpu with a similiar performance?
