The "C"-shaped motherboard comes out easily. Rather than using daughterboards like the Droid 2, the Streak has all components attached to this singular motherboard.

This is most likely due to the extra space afforded by designing the Streak around its 5" LCD.

A 2 GB non-user accessible microSD card can be seen near the top of the motherboard.

This card is used to house system & applications files only, and Dell doesn't want you to remove it.
