A Reader's MacBook Has Thermal Grease Leaking Onto SO-DIMM Slots

Reader Amin's ran into a bit of trouble when he went to upgrade the RAM in his fancy new MacBook. He writes:

Hello, i'm a long time gizmodo reader, I've ran into a big issue with my MacBook in where the thermal grease applied to the internal components has leached into the RAM slots on my motherboard and have 'soiled' the DIMM's with thermal grease...

Has anybody else run into this? Or is he just the unlucky victim of a sloppy assembly plant monkey?
