Custom Build help

I have the following specs (custom build):

1) AMD Athlon 64 X2 5400+ 2.8Ghz Dual Core
2) ASUS M2N68-VM Motherboard
3) Powercolor ATI Radeon 3850 (512mb)
4) 80GB IDE hard drive
5) 4GB DDR2 Memory
6) 1xDVD-RW +/- Sata IDE
7) 1xDVD-ROM IDE

My friend and I tried multiple times to get OS X on this. He was using iATKOS v7, with a bunch of kexts we found. We got a kernel panic after the install finished, but couldn't recognize what the panic was from. Upon restart, OS X booted up, bringing us to the registration page, which I filled out with no problem. Upon getting into OS X, the main problem that was visible was the video kexts. When we moved windows around, the outside disappeared OR left trails. We installed all the kexts, but when we restarted, we got another kernel panic. I'm thinking that it is due to the IDE hard drive, but could it be that I need to use iDeneb? Also, is a boot 132 possible? I have a retail copy of 10.5 Leopard.

If it IS possible to get Leopard working, does anyone know if snow leopard is possible?

for any and all help.

PS: I have some experience with installing OS X through iDeneb (both v1.3 and v1.4 on my EEE 1005HAB).
