external monitor on 5500
i have this weird idea to attach an external monitor to my 5500\225. i want to give it a paint job and upgrade all the insides while releiving my work space of two other macs. basically i want to consalidate my desk to just the 5500, since it has only a 15"mon, i need bigger for my graphics and art needs. i have a 17" - just my size, and don't want to loose it. i see everywhere all these two mon'ed comps and was thinking of doing this to my 5500. there is nothing wrong with its mon, i just want that nifty two mon wrap around.
let me know if i am a retard and should never be tried. or if it is possible, any ionfo would be appreciated.
peace and love
