Noob build advice

Here's my specs. I came here to see if these would work. I was looking towards a Mac Mini-like build, and perhaps take on the task of putting these exact if not similar components into Mac Mini housing from 2007-09, because I want to, ideally have an optical bay for a bluray player. I sometimes do plenty of graphic-intensive work as a hobby and since I've owned a Macbook Pro for five years [2011], I was figuring on making a desktop build that would be within a 1000-1300 budget.
