about to build a computer for recording

[texshred777]

Well, Im about to have a friend of mine build me a computer for recording. I'm going to actually put in the sound cards made for recording/mixing that also have mic preamps and inputs as well as outputs and whatnot. Im not exactly sure where to start. I also need really good software for making all backing tracks. By the way, im experienced in composition, so ill be using finale for composing a lot of backround stuff, if that helps. Any rec for the actual cards and software i should use or package deals easily findable in say a musicians friend catalogue. Im not sure id use other drum loops, as i have a good compositional skill level and the ability to write my own complete drum parts...but hey if discrete drums or acid pro or soundforge work well for the verse parts or choruses great.
