I was wondering if the below upgrades were correct for my Late 2008 aluminum macbook. I am upgrading the RAM to 4GB and upgrading the HD to 500GB. Is the RAM the correct type? I am assuming it is because OWC's site is pretty easy to navigate, but I want to make sure before I order. Also, I have been reading that WD is probably the most reliable/purchased HD option. Do you agree? I only have about 100GB on my current HD, but plan to install Windows 7 soon and have at least another 70-100GB Windows partition on the HD. Also, about the enclosure I purchased: Would it be safe for day to day time machine backups? It doesn't look like it has the best cooling, but I dont know much about external enclosures. Finally: What screwdriver will I need to access the RAM in my Unibody? This is the model with the removable HD so that will be very easy, but I am under the impression you must take off the whole back panel to access the RAM slots?
