How can I tell if a downloaded copy of OSX is from the original DVD?

Sometime it is easier to download from the web than to look into the CD box. The main issue with downloading is that most likely the DVD is not the original and has been tweaked or customized.

The best way to know if the DVD is an original copy is to look at the MD5 checksum.

So here we are starting a list:

Image MD5 Checksum
snowleopard_10a432_userdvd.dmg 817F2D9CFB56885D6E8E3FD99855B691
snow leopard retail 29$ 817F2D9CFB56885D6E8E3FD99855B691
