My usual technique to deal with these sort of brick and wall-wart PSUs 
that are glued together is to carefully squeeze their plastic sides in a 
small padded vise to break the glue joint. With practice, you can split 
one of these open with little to no damage. Don't be tempted to use a 
mallet as you could with really old linear transformer wall-warts though. 
The g-forces generated by a mallet will break components off of a pc board 
in a switchmode PSU.
