Compatibility

[the803]

So I'm planning to install OS X, most likely Leopard 10.5 and I'm wondering if all my hardware's are supported and hoping that I won't run in to any issues.

Processor: Intel Core 2 Quad Q6600 2.4GHz
Motherboard: Gigabyte GA-P35-S3G
RAM: 2x1GB Crucial PC2-6400 + 2GB OCZ GOLD PC2-6400
Hard Drive: 160GB Maxtor HDD IDE (With SATA Converters)
Graphics Card: PNY 8400GS 256MB
USB Wifi Card: TP Link TL-WN322G

Main thing I want to know is about the Wireless Card but would like feedback on the other stuff too.
I would also like suggestions on which version I should install?
Thanks,
