It seems to be extremely hard to get a road case for the Gaia, at least in North America.
Luckily I have a number of guitar hardshells kicking around. One inparticular was ruined by the girlfriend's cat years back. I had to rip some of the interior lining out to get the smell out, which left a surface that's a little rough to be putting a guitar body against.
One snowy night i needed to transport my gaia to a gig and did not want to bring it in the cardboard box, so I iprovised with this guitar case. The only modification I made was to knock out one wall of the middle compartment with a hammer.
As you can see this left me with a perfect sized space for the Gaia to sit snuggly in and an extra spot to fit cables etc, or in this case my electribe.
This case was for an Ibanex S-540 but I'm sure it's just a standard hardshell size.
