At least this thing is a Mac

I've seen the iPod apple stickers on anything from cars to PC desktops and laptops.

Bought a soldering iron today (instead of always lending one), got the bottom 2 screws out and the battery screw, but the top 2 screws are difficult because they are very recessed.

Screwdriver bit extensions just spin or get stuck.

Is a long T15 allen key the tool for this? I have a regular one but it wont give me room to turn it.
