Mobile WC Rig?

Ok, my next setup I am building (after this one, lol) Will be a small custom LAN style case, ala the custom guide in alternative modding. I want to Watercool this, for both Performance and to show it off...But mostly to show it off, lol. Is there any setup that this can be done with, or a custom way of doing it? Maybe with hard lines of some sort? Input is the name of the game all! Thanks
