If you do use a Bic pen, make sure you get a clear plastic one. The opaque ones are made of a bendy plastic that tends to strip when you use it for screws. If all else fails, you CAN buy a bit or screwdriver for those screws, but they cost like $8 apiece, so I'd go with other methods. Being a portable-izer myself, I know many places to find info on these types of things. Best is http://www.benheck.com

). I believe the hemostat and soldering iron methods are the best to use if you don't want to damage the case. I used neither of these, rather I took a normal flathead screwdriver and filed a groove that fits around the screw. Took like 10 minutes, and it'll won't break after 5 screws.
