Remove Keys and remap keyboard layout

Hey,

First of all, this site is awesome!!! THANKS

Now to the point, is it possible for me to take out the keys on my MBP and then put them back in? I would like to re-arrange the keyboard into a Dvorak layout.

I did some searches online and found this, http://www.flickr.com/photos/stephenwals... But this is on a much older computer and I am not sure if apple has changed the design of the keyboards.

Anyways, if this is possible, then please share or even make a short little guide. I have started to try this but i am too afraid of breaking my $2,500 machine!

Thanks

And to clarify, I would like to physically take out the key caps and put them back, into the Dvorak format. I know that i can change keyboard via System prefs>Language&Text>Input source>Dvorak
