I've built a couple of machines now, and found it best to try and build a 'virtual' machine and ask opions here after doing that. There is so much scoope now for the money you are willing to spend, asking members here could bring massive options and bring you no closer to a solution.
I suggest using a reputable vendor eg Ebuyer, Dabs, Cougar or others that are recommended here and elsewhere, then gain opinion on compatibility, quality etc.
memebers will try and help, but I'm not sure there will be many willing to do the legwork for you.
Check out Cougar as a start at least to give you some idea, it's a very friendly site to 'build' your machine.
