A few months ago just upgrading the memory was daunting. Now I am replacing hard drives! A #1 Philips screwdriver works well on the panel and case screws; it's hard to find a #1 by itself, but Radio Shack has an under $7 set of flat and Philips screwdrivers sized just for netbook work. A magnet is a mixed blessing. Our screwdrivers are supposed to be NON magnetic so we don't disturb anything electronic (I don't know what would get messed up by the mild strength of a magnetized screwdriver, but I'm not taking chances ... yet) but a magnet, just a refrigerator magnet, is a great place to put the screws you remove so you don't lose them. On several occasions I've had screw bounce off the kitchen counter onto the floor. I found all of them...but one...my harddrive carrier now has 3 instead of 4 screws, don't make the same mistake! When you remove anything, make sure you note and remember whether screw tabs go over or under, same with wires, and remember order of disassembly. Fortunately netbooks are electronic widgets and not grandfather clocks or aircooled VW's, so there really aren't many thing you have to unscrew to to significant replacements and upgrades (upgrade memory, replace HD with SSD, add mini PCIe video accelerator card). If you order a Broadcom Crystal HD BCM70012 card, ask for mounting post screws!
