GTA02 C4110/1 replacement?

[Al Johnson]

Some time ago Joerg (IIRC) suggested it might be possible for the 
brave/foolhardy to replace the undersized caps in the headset output with 
something more suitable, or even with audiophile esoterica like Black Gates. 
Looking at the schematics I see these are C4110 and C4111 which appear to be 
located under the can that has the bluetooth module stuck to the top of it. 
So how easy is it to open and close this can without breaking anything?
