Hi, I'm having a hard time deciding between the ATX chassis or the mATX chassis. I know for a fact I like the simple clean look of the fractal design define series. I don't plan to overclock, nor do I plan to set up dual graphic cards SLI/crossfire. I do plan to game and use CAD/editing programs for this new build. I'll be placing the case on my table so I don't really want anything too overwhelmingly big next to my 22 inch monitor. Thanks!
