It's retail, but also have Leopard & Snow leopard. Tried booting from all with external player.
Ejecting DVD: Had Snow Leopard trapped inside, nothing would get it out until I poked around the DVD slot as I switched it on. Out popped the DVD so though I would try a different OS version. Tried mouse, eject but machine will let nothing happen
