Ok first here are my PC parts..

Asus P6T SE
Realtek HD Audio (onboard the P6T)
Core i7 920
6 GB OCZ 1666
Radeon 4890 1GB
Realtek RTL8168C Gigabit Ethernet

Dont have any dvds either, but have 4 hard drives. Wondering if I can use a 2nd HD in my comp or do I need to use a hard drive enclosure.

And if by any chance, I would like to run Snow Leopard using VMWare.

Ive tried searching the internet on how to install . just too all over the place and im busy all the time !

I'd appreciate the help. Thanks in advance!
