Reply to Laptop for video & audio DJ-ing

I need a laptop for mobile dj-ing. I would like it to have as many output options as possible, rca video, s-video, hdmi, vga - rca audio, usb, 1/4 in. or mini, xlr. I know its probably not possible to have all but any assistance on how to go about purchasing or building a custom machine would be GREAT!!!!

Thanks'
