I love my Virus and would never sell it! So whenever I travel with it I use this case. At least im pretty sure this is the one:

It is built to Military spec. At least mine says it is. Shock proof, waterproof, can drop it off the freeway and the virus wouldnt have a scratch. Has customizable foam insert to custom mold to your instrument. I can easily fit my Virus TI Desktop in there with its power supply, and all its cables. USB, TRS, etc. And still room for a mic or other small items. Can fit a slim controller in there too if I reworked the foam in the right way.
