I've got a Dell Inspiron E1505 / 6400 running Fedora Core 6. The 80GB harddrive is a bit small for my needs, and I'd like to replace it with a 160 GB unit. If I buy a hard drive locally and install it myself, will I void my warranty? I do have extensive experience working with computer (mostly desktop) hardware.

Also, if I simply open the computer to look around, will I void my warranty? I'm especially interested in cleaning the airways, as the lappy gets hot and googling the problem leads me to many others with hot Dells who recommend an occasional cleaning.

Thanks in advance.
