Simshell,
Quite honestly buddy you might want to invest the time and money in having someone who works on computers for a living to install this one for you.
BUT other than that how is the card to long? What size case do you have? (ie...full size, mid-size or micro AT [shudder], ATX again full, mid or Micro-ATX) Is your case a desktop case or tower? Several things we need to know here along with which motherboard/CPU you have and is it a store brand system (HP, Compaq, etc...) or is it a Dell, Gateway, etc...
