Building my fist PC!

Hello, I'm a newbie seeking to build my first PC. This is mainly for music recording Graphic design and video editing. I've always wanted to build a PC and partly I want to see if I can actually do it. My goal here is a quality desktop that I will use for a while without have to update a lot or anything. I will be running the adobe suite, fl studio, adobe Audition, and melodyne. I to be able to have multiple monitor and to run tones a programs at once.

Someone please help thanks in advance
