Cooling Pressure loss in a bladder?

I have a very weird style case I am trying to mod, I was wondering if there would be any problem using a "bladder" type reservoir instead of a hard plastic or acrylic one?

I have some ideas what I want to do with the case but unfortunately its in storage miles away until spring.

 

Should be fine tbh. As long as it's rigid enough not to get sucked into the outlet, you shouldn't really see any problems.

 

Yea it will be pretty tough, thinking of using a army style camel back type water skin. I'm trying to find one thats clear but so far they are all clouded.

 

Congratulations!

You just urinated

 

Well, isn't there the possibility of deflating it in the case of block restriction or some odd?

turpija built a window reservoir to save space in his project (water cooling for everyone), you may wanna have a look there.
