Hello, I've lurked on the forum a bit but finally decided to register and ask some questions. I have a black s10 running OS X 10.5.6. I took a 1gb stick of ram from my sony laptop (Which has been giving me alot of trouble), and also came across a mint condition sony CDRW/DVD laptop drive for free. I picked up an enclosure for this for $12 and also a hitachi 320gb 7200rpm drive for $47.99 after rebate, so in total i've put about 60 bucks into the s10 and come out with a pretty "upgraded" s10.
