In deed it does (for the button that is). I usually fit the hole with a short domed hexnut M3 screw and put a nylock nut on the inside to prevent it from falling out. Then just press the screw from above to reset...
If by reset pins you mean the 6-pin ICSP connector next to the u-SD slot, then those are also accessible.

Attach heatsinks onto the stepper drivers
Attach a fan and a "fan grill 40mm" (just search for it here on thingiverse: thingiverse.com/search?q=fan+grill+40mm) with four M3x12's screwed directly into the case
The enclosure can be attached to it's surroundings by cable ties through the four rectangular holes in the bottom part
- The slot hole for the microSD might be a bit too small, but it's easy to cut away approx. 1 mm from the top part of the enclosure to make a better fit for the card.
- Also you might want to attach a piece of tape to the rear of the microSD card so it will be easier to pull out.
- Hopefully next version of the PrintrBoard will feature "push-to-eject" (https://labitat.dk/wiki/Printrboard_amendments)
