@McLovin - I spend way more time messing with my cat than I do with AutoCAD. When I am actually using CAD, I usually just draft objects to fit a specific sheet size, then print them out later. My printer isn't even connected to this setup; it’s hooked up to a different computer somewhere else in the house. Last time, I just lugged my laptop over to make things easier.
@Robert Rodriguez2 - I've got a mouse since it's attached to my laptop right now, but I'm missing a keyboard. As for audio, I've just got some tiny Microsoft speakers, and I don't have a monitor either.
I went with an all-in-one bundle—basically the tower, keyboard, and speakers all together. Looking back, I think the whole thing cost me somewhere around $4,000.
