Yeah, It'd definately be worth it, especially for end-users with a ton of AC stuff plugged in!!! But something like this would (probably?) take a while to develop since it might not be the biggest market for it really (although there are quite a few people who probably could benefit from it, instead of using an external USB port and routing the wire back into their case, ugh!!!).
But! In the mean time, I was doing some searching and found this guy who put up a blog about how he made his own internal USB hub:
http://www.ultramobilegeek.com/2007/08/a…d-internal.html Now, he's doing it in a laptop so that he can install a bluetooth reciever inside, but it's the same principle. Just basically look at the first few pictures. Here's another site where the guy did it a little bit simpler: http://www.tygatech.com/Project001/ . At least the pictures are a little easier to follow.
He just used an old 'flash-drive' type hub that is the small portable ones (without the need for a power connection). And then you basically swap out the ports and solder on wire connections to your actual device (or an internal USB connector port, then plug your device into that).
But anyways, the point is that this is small enough that you could mount this in some kind of way behind or next to the aquaero (may take some jimmy-rigging). And then you could just run a single wire from your motherboard USB header and up to where this is behind your aquaero. And all your connections would be short and the wiring hidden within the drive bay slot behind the aquaero!
