Need assistance piecing together my home workstation (4x 7950's, i7)

[jbreed]

Well I have been in the IT field for a while, but stick to the networking side of the house. I have a background in network security and would like to build a rig that I could use for brute force and/or litecoin mining (figured I might as well put it to use when I'm not using it). I am not a novice, but have never pieced together a workstation for performance. I do not need it rack-mountable since it will be sitting at my home, but I do not want it open to the air (needs a case). I have a budget of roughly 4k. Needs to be fast at video editing as well.


What would you buy?

I have a Fries roughly an hour and a half drive, but don't want to go there and buy shit that doesn't work together.

Was thinking the following:
4x XFX 7950's
1200watt corsair power supply
i7 3770K ivy processor
16G DDR3 2400 G.Skill ram
No idea on motherboard?
No idea on case?

you can search for the boards that can handle 4 gpu's (you really need 4? though i know its for bitcoins)

the top boards are asus, msi, gigabyte, asrock. there are only a few boards that can handle 4 gpu's

well you better have a list of board that can handle 4 gpu's (you really need 4? though i know its for bitcoins)

Do I need 4? Probably not, but why not?

I was looking at the ASUS Sabertooth Z77. Also, what would be a good size case to allow good cooling? Will be running a water cooling system as well.

I will probably be running a list of hashes maybe 1-2 days out of the week. The rest of the time it may see video editing, possibly gaming, or might get into litecoining.

If you are planning to build a dedicated litecoin mining rig, the instructions here are pretty good. However, I noticed they show an AMD based system with fairly low powered CPU and you're looking to build a higher powered multi use rig. You'll definitely want a large case with plenty of fans to keep those 4 GPU's cool when mining!
