Of course you can make, If you want to.
What I did with mine
2 top exhaust fans are 200mm led blue (I replaced the black one)
I left the front fan alone
Power fan I replaced is 140mm Blue
Side 200mm Fan I replaced with a 200m Led Red Fan and removed most of the shrouds
The top of the door panel I bought a pack blue cathode light and attached it to the door itself
The bottom same thing but with red
For the liquid cooling on the top, if your doing CPU only on the rad, do a straight blue, if it all stays in the top side that is. (As a first timer I personally went with clear, but I think the color tubes look more awesome.)
If/when I do a GPU on a separate loop I would use red tubes for the GPU Loop. which kinda makes sense because GPUs run hotter then anything. If on the same loop, you could always have the tubing attached to the GPU red, and everything else blue. Rad>Blue Tube>CPU>Red Tube>GPU(s)*>Red Tube>Pump>Blue Tube>Rad. *If running more then one GPU you should probably invest in another rad to handle them.*
Basically you keep the theme consistent with the top video card a a divider between the two.
If you do want a one tone scheme, Red with the Haf X is a Fantastic choice, especially because you don't have to replace or turn off the front fan to keep the scheme. I couldn't decide between the 2 so I did both.Edited by Skilletis - 2/5/13 at 11:49am
