[Cube] How much force can I use to pull my Cube apart?

[John Anthony]

Do not force the chassis out of the enclosure, you will do more damage to 
the cube. This happened to me once also. I used a rather thin plastic 
spatchula <pancake flipper> to release whatever was holding it. In my case 
it was the airprt door was not latched all the way. I worked my way around 
the case, and it gave up and released. I hope this helps.....John A.
