InfiniteMac OSx86 - Please help, Total Noob

Hi all, having previously owned applemac's for years, I recently moved to the dark side and went for a PC.

Now I have done that, I am missing OSX like mad. I am currently running a dual boot with Windows 7 x64 and Ubuntu 11.04.

It is Vital I keep my windows Installation, so a dual boot between OSX and Windows would be ideal.

I have never installed OSX on a PC based system, and am looking to install it on both my laptop and PC. (Prefferably Snow Leopard, but Leopard will be just fine)

I have the original Installation discs, from when I had my last, mac, unfortunatley I dont have the Mac anymore! (it died)

Anyway, not sure what info you need, but here are the two systems I would like to run it on:

1> My Laptop - A Sony Vaio VGN-FZ21Z
CPU Intel Core 2 Duo 2.2GHz
Display15,4" 1280x800
HDD 300 GB 5500 rpm
Memory 4096 MB
GPU NVIDIA GeForce 8600M GS 256mb
WLAN 802.11a/b/g/n
LAN 100Base-TX
Optical drive Blu-ray

2> My PC - A Custom Built System with the following:
Gigabyte GA-890GPA-UD3H (rev. 2.1) - motherboard - ATX - Socket AM3 - AMD 890GX
AMD Phenom X6 1090t CPU
16gb Corsair Vengence DDR3
128gb OCZ Agility 3 (Sata III) SSD
1tb Samsung 7200rpm HDD
Blu Ray Drive
Onboard Graphics (using HDMI), Sound and Networking.

Any Advice would be greatly appreciated. I have used many google searches and Wiki etc... but am finding many discrepencies in installation processes and hardware support.

Thank you in advance Ryan
