My relatively new 13" MacBook Pro is starting to give me the beachball when working with professional programs. I ordered it with 2GB of RAM to save money and upgrade it later. What I would like to know is if there is a website or store where I can order a replacement bottom cover and screws. I didn't own a case with it originally and it sustained quite of few scratches and dents. Also, the rubber feet are no longer balanced. I've saved up more than enough for 4GB of good RAM at newegg.com, I was just wondering if I could go ahead and replace the bottom/battery/ram cover while I'm at it. Thanks in advance for any info or advice you can contribute!
