The value of an AU wheely to us yanks isn't nearly what it could be because it's virtually impossible to ship it to the USA for reasonable $$'s. The size exceeds what the post is gonna accept so it will probably have to go UPS or other high price shipping service. So like Rick said, it's a fairly common box in AU but since that's where it's destined to stay, the USA value is rather meaningless.
Then with regards to customizing -- I disagree that custom boxes necessarily degrade the value. It really depends on the final result and how it was done. That Conion that was mentioned above -- YUK!
But I find it hard to believe that these guys here are worth less now than for what I bought them for.

And there are some that I have not yet shared, and there are probably some that I have forgotten about and/or left out.
In any event, each and every one of these -- I highly doubt is worth less than the original product. Some changes are very subtle and maybe not immediately noticeable. Some are more flashy and is immediately apparent that it's not original. Yet, I believe each restoration, modification, retrofit, upgrade or customization was done tastefully. Each one was carefully considered before proceeding and each one of these is and likely will always be inherently UNIQUE and worthy of a superduper badge. I must tell you that each job resulted in great personal satisfaction and joy to myself and/or the new owner. So I reiterate: As long as the work is done tastefully -- GO at it.
If you are thinking stick on skulls, texas style horns, contact papered shell and space taped handles -- well, also do it, but keep it to yourself.
