I would like to use CAD if I can ever manage to get my hands on a (free) copy of it (being that it costs thousands). I took a course in high school and even if I'm not gonna be an architect, it is still a very useful program for things such as designing the show-room at work. the 1GB memory cards were only $40 each, which in my opinion was a steal, the cpu was less $ than an e6700 from a regular retail store (I purchased a good majority of the items from eBay and everything was brand new that I got). So even though it looks like i splurged and went crazy on the processor and memory, I really kept it more conservative than if I would have bought it all from someplace like Best Buy or CompUSA.
