I need to build a SMALL PC with dual video cards to allow me play videos in PowerPoint using extended desktop. Currently am doing so with laptops with many problems playing videos again in extended desktop. Want to contiune to use extended desktop so I see this as my solution. Yes and I on the right track? So, do you know of a small box I can jam in two decient video cards and a good processor to fit in a carry on bag to skip around the country doing my AV thing?
