I have an HP Dv7-1245dx that I want to install Snow Leopard on. How should I go about doing this? I'm new to this idea and need a lot of guidance. How can I obtain a copy of the OS? I am very tech savvy, I am a PC technician but I have only worked on Window's machines. Please, and help would be awesome!

Here are the System Specs:
AMD Turion X2 Dual-core Mobile RM-72 (2.10 GHz)
4 GB Memory
64-Bit OS (Even though it doesn't matter because the OS will be wiped off)
1 MB L2 Cache Memory
ATI Radeon HD 3200 Video Card
