The little light on the front cycling dim to bright means your Mac is sleeping. That is the normal behavior. I keep my Macs running continuously for weeks and even months at a time without ever having to reboot. Usually only have to reboot after an OS upgrade or such. We have: iMac G4, G4 dual 1 gig tower and iMac G5......also a 12 inch powerbook but it's off most of the time. They're all running 10.3.6.
