'Maybe' but it's not a best practice. The fan on the 13" has a panel that extends far beneath the heatsink. And the tiny ribbon cable that connects the fan to the logic board is very difficult to unplug with the heatsink attached. If you can manage to unplug the ribbon cable without remove the heatsink, then yes.

Yes...Don't know if there's ever been a macbook with an upgradeable processor...that's typically been reserved for their desktops.

Sure there is! Is it feasible for you to do or economic for you to pay for someone else to do? Nope! Check out Dosdude1 on youtube...You are likely limited to dual core 4th gen cpu's due to the TDP constraints of the 13" laptop though.

Great question...no one knows! Check out the discussion here: Tape over processor and GPU?

I feel like this score (as well as others) deserve a revisit. I am a moderately seasoned technician and I have gutted an entire 13 and 15 inch retina MacBook Pro. What are the main differences from the unibody's?

1. Proprietary SSD (alleviated via a cheap adapter)

2. Soldered RAM (the biggest bummer; but still possible to upgrade and I HAVE: see REWA and iBoff RCC)

3. Riveted Keyboard (Another bummer, but not that impossible to replace; and after replacing? You can use screws!)

4. Adhesive for the battery (I removed both 13/15 batteries WITHOUT heat or adhesive dissolver; I did need to remove the 15 Logic Board, so that is certainly a time consuming repair)

5. The screen assemblies are basically all one unit, any issue means you are replacing the whole thing for most people (but even on the unibodies...who was replacing individual components on these screens? That's crazy risky)

Other than that? Everything is just screws and connectors...borderline identical to unbody's. 1/10? Give me a break...

Does the gasket reapply easily? It seems like once you get it off it wouldn’t like to go back on.
