Ok, sorry, I think I misread also, I am now guessing you want to see the cover in situ in a case rather than how it would look with tubing coming out of it! Cannot help there but bear in mind that each cover will use up a 125mm fan hole and you would need 2 to route tubing back and fourth. That is another reason for a DIY approach. Grab one of the plates I mentioned above and make 2 holes in one plate. You can easily pick up grommets of various sizes if you just want to feed the tubing through directly.
EDIT: Apologies, they are sold in pairs! But will still take up 2 120mm fan holes.
