    I have a 27" (Late 2009) which i'm going to get rid of soon to upgrade to something newer, however i have Mountain Lion installed on it and i want to do a clean install of Snow Leopard on my mac. I no longer have the Snow Leopard Disks that came with my iMac, would buying a Snow Leopard disk from an Apple Store fix this, and how would i perform a clean install.

    Apple will sell you a replacement RESTORE disc for about $16 if you call and give them the model and serial number of your iMac. The Snow Leopard retail disc costs about $20.

    Either version should work to reinstall Snow Leopard after an erase.
