what customization are you struck at? choosing kernel? or drivers or anything specific?
List clearly your video card, audio card, Chipset, then for the list appropriately choose the right drivers. If you dont find appropriate one, try the forum, They might have the answer. you can choose Vanilla kernel or the voodoo kernel. my suggestion would be voodoo, though ppl feel "Sexy"(ok..atleast some..) using Vanilla kernel.
u may sometimes have to try different combos on drivers if it things dont work. Be aware, it is time consuming...some times frustrating..most of the times u may have to reinstall multiple times.
