My laptop has been having overheating problems, and I want a desktop since I rarely use my laptop as anything but a desktop. Looking to spend under $500. It looks like a lot of systems for ~350-450 have onboard graphics so I'd have to install a graphics card to run multi monitors, which is fine. I'd mostly be using it for poker, word processing, and intertube browsing. Storage isn't really a big deal for me as I have stopped hording movies due to netflix and stopped hording music on account of getting a pandora subscription.

Is PCI-E pretty much standard on motherboards now? Some of the refurbished systems I've been looking at don't say what expansion slots they have.

Heres one I've been eyeing, obv it would need to have a graphics card installed. Thoughts?
