not added it yet

Yes, that's an acceptable choice if you desire to have the colour scheme.

I should work fine then, I hate motherboard shopping. don't understand. I can beryl find something with the right socket. Also if I do add more fans either the same that is in or cosair air series af 120/140s how will I get them all to work off the one 3 fan controller built in. The room I want to put this in has a large wall mounted tv so I love to connect it up to that to have a nice htpc. It's not a priority btw just wondered.

You can attach multiple fans to each header. Use a 3pin splitter. I have a 6way braided cable that I bought here:

They have a nice selection.

My final build, if your interested. Swapped out the ram, and mobo:

Massively over budget but I can't help myself. I see it, I want it 

I was wondering about dual-booting osx which would require a intel processor. Its more but the motherboard is less so it averages out:
