There's no restriction in the GPL to prevent you from selling things. You just just can't prohibit the buyer/recipient from redistributing it under the GPL terms and you have to make source available. Some of the other licenses are different, but none prevent redistribution and none that I know of have terms that would prevent that redistribution being a sale.
Copyrighted artwork would have to be changed.

Ok thank you everyone. I have a second question.
My business strategy will be based like Red Hat on selling support and updates to clients. The most comfortable way for the users will be only to install the made software on empty server and to start using it. To do this I need a way to let the client to enter serial key before installation like Red Hat does. Is tis source code available on Internet? Where I can find information how to make this on Centos?

Centos uses yum instead of RHN for updates, so you'll probably need something different for this. You might look at whatever ClearOS is doing - they have both free updates and a paid subscription support model - with mostly-Centos packages under the covers. Earlier versions imposed some limits on use in the free version but now I think the subscription is more about extra service-related features.
