Have you backed up any important data yet? Have you ever been inside a case before? I ask, because I don't want to bore you with details, nor do I want to assume you know something, when you're not clear on it. Getting inside a box is easy and should not be a problem if you follow the basics. Clear a workspace, have a plan, ground yourself to your box, then flip switch on the power supply so you cannot accidently turn the machine on. Some say to pull the cord, (I'm one) Some say the box is no longer grounded if the cord is pulled. I pull the cord. That way there is no power to the motherboard so when I drop a screw on it, it won't short out. Never use alot of pressure on anything. Most computer pieces fit firmly, but should never be forced or bent. If you mess with the CPU fan, before you turn the computer back on, make sure the cpu's fan is plugged in, otherwise you may smell something rare and expensive cooking.

Finally, never put your side back on until you have tested your new mod or up-grade. I guarantee you will have to remove it again to reverse your floppy cable or something else silly. ;D
Really Finally this time: Read these websites. Voided Warranty goes to alot of time, expense, and effort to post article and how to's. Make their effort worth it. You'll not regret it.
