First of all, if cooling and having lights is important to you, you need to get another case. www.newegg.com
Has some great colored cases that have a plexiglass window in the side that will allow you to see into your computer. These cases usually come with some sort of neon lighting that will make the case look very good. You can also pick up some lighting at any store that carries quite a bit of computer equipment. The more fans that you have the louder your case is going to get. Put a fan in the front to intake and two in the back for outtake should be plenty to get the air circulating. Many people freak out when their system gets hot, but around my 9800 XT and P4 it is usually about 104 or so.
