yupe replace the monitor, keyboard and mouse.

keyboard is cheap anyway.

also get a usb mouse (optical ones if u can) switch from serial to usb or even ps/2 mouse is MUCH smoother. especially with winxp
its worth the extra bux. it just won't feel good haveing a spanking new system and an old kybd/mouse sticking out.

get a new 19 or 17 inch monitor. they not that much these days anyway. since u u sing a P166 before, I figure u was using a 15 inch monitor?
