It would seem as if
Pelican's 1020 Micro Case would be perfect for making the X5 quasi-bulletproof. The interior dimensions of the case allow the X5 to fit with room to spare (for padding):
5-3/8" x 3-5/8" x 1-11/16"
(13.65 cm x 9.21 cm x 4.29 cm)
Anybody travel with their X5 in a Pelican 1020 when a little extra armor is needed?
