building a pc desktop computer

[captZEEbo]

If anyone can link me to some nice review sites, that'd be good too.

I'm not sure what motherboard/processor would be best for me, but I basically want a really good one.

Some requirements:
as many internal sata slots as possible.
can hold 6+ slots for hard drives/dvd drives
5+ usb2 ports (possibly it might be better to just put this as a pci slot? not sure really)
anything else I should consider?

memory:
what's the best kind of memory to get? I'm going to want at least 2gb ram, but possibly more.

video card:
what would I need to play a game like cs:s? Do I need dual graphics cards? Should I consider getting a motherboard with nvidia or whatever built in?

cooling:
worth it to not use fans but use alternate method?
