Basic prebuilt Windows 7/8 system capable of or can easily be upgraded to support three monitors; and need a monitor suggestio

[joek1997]

I'm looking to buy a basic prebuilt Windows 7/8 system that is capable of, or can easily be upgraded to support, three monitors. I have two monitors that would need to be connected by VGA or DVI. I'd need to buy a third monitor -- I'd prefer to use HDMI for it since I already have some spare HDMI cables. I started looking and it seems like I just need to get a system capable of using the ATI 5450. Any general tips or specific system/monitor recommendations would be great!
