thanks krusher. it seems pretty much everything is gonna go in through the usb and firewire ports: hard drive, optical drive, keyboard (most likely a frogpad), trackball , and any other peripherals. as for the lcd glasses, i want to go a bit further than that and get a higher-end HMD. one that can do 800x600 resolution. fortunately my budget is designed around that, so now its just a matter or finding the cheapest one. i also want to get a webcam (an isight would be wonderful, just because of its size) and mount thatto either my shoulder or the HMD adn "see" through that. if i do keep the monitor, it will serve the purpose of showing others what im doing and seeing.
