Help I want Mac on my PC!!!

Ok basically im fed up with Windows... I'm pretty much ready to bomb Microsoft at this point...

This is what I have:

AMD Athalon Barton core 3000+
PC Chips Socket 462(A) MOBO
2 Gigs of 400ddr 184pin A Data ram 2 sticks at 1gb
80 Gig Jupiter HD 5200rpm non sata

Can i possibly go with Leopard or even Tiger on this OS?
Shoot i mean i would even go with Linux anything at this point to just get away from Windows XP...

Any help would be great!
