Yes, you are certainly permitted to rebrand Centova Cast(Centova dedicated server / Centova VPS) . -- we do not provide support/assistance with editing the templates/CSS, nor with any problems that may arise as a result of modifications that have been made. But for Centova resellers you can change your Logos and names using your Centova reseller control panel .
Modifying the Centova Cast interface may interfere with the operation of Centova Cast, and cause issues to arise which may appear to be unrelated to your modifications. You can use our hire server administrator service to hire us to do that for you
