Or better yet - put GBC in DMG shell. It's colorful, some people (including me) like its sound better + all the points above.
And you can replace the contrast wheel with the front light brightness adjustment wheel - thus even the jacks are correctly labeled.
The latter is actually the reason why I don't like to putting SP into DMG. All these holes (contrast, link port etc) are different and it's obvious that the shell was not made for it...
However I'm not sure GBC link port is the same dimensions as DMG port, so maybe it's no a good idea after all... I need to get home to check all that.
FIY I'm writing it down because I'm procrastinating. In reality I have shit load to do
