I have been considering buying a coolermaster haf xb, but what i want to do with it when and if i get it is send it off to a company to get it painted like one of those cubes from portal
I am not sure what you mean by “portal.” Please excuse the old man’s ignorance on this subject. As far as painting goes look for a reputable powder coater as the paint job from that method is second to none.
Ok, thanks i meant portal as the game made by valve 
thats the design i want to have the case painted as, but i don't know if someone can do that

I see why you might like that on you case! Very cool indeed. I think you would be looking at taking some pictures to someone who can do airbrushing as this is very intricate work and no one wants to hear the words oops while trying to do that kind of paint job. Check the work of some guys who do motorcycle tanks and such. A lot of them are very talented. Of course this is not going to be inexpensive when you are dealing with custom hand paint jobs. Let us know how it turns out as I for one would love to see the results.
