I want my computer to be in the basement, but to use it on the first floor. Which cables should I run through the floor? Can some be wireless or other methods?

Here are some of the options I've thought of:

Basic: Run DVI, usb (mouse), usb (keyboard), and audio cable (4 cables)

USB Hub option: Run DVI, and 1 usb, then using a usb hub split it into mouse, keyboard, maybe even audio (2-3 cables)

HDMI Option: If I get a new video card and monitor that supports HDMI, would I be able to run both audio and video through it? Would the monitor have to have an audio out? Also there is a lot of extra bandwidth in the HDMI cables, could I send two monitors on 1 cable or would I have to use 2 cables? How about sending mouse/keyboard through the HDMI cable? I see a lot of monitors with USB hubs built in, but I assume I'd still have to wire HDMI + 1 USB cable to use the USB hubs?

X Terminal Machine/Thin Client: I don't really know much about this option. Not sure if it would allow me to run graphics acceleration and watch movies, does anyone know more details about what this would allow me to do?

Other options: Any other ways to do this? Can any of this be wireless?
