Any chance of a VGA Card Air to Water Conversion Tutorial?

I bet that like me there are lots of people who have air cooled Radeon R9-3XX or Radeon R9-4XX VGA cards,

and would like to convert them to water cooling for that little bit extra punch.

 

Has anyone done this type of conversion?

And would like to post a tutorial so other members who would like to have a go can do so?

 

Is it possible to 3D print the necessary component parts?
All except the pump block?

And indeed, would it even work if the parts were 3D printed?

Or is that simply an absurd idea?

 

 

Or is it better to purchase those items over the counter?

 

Thank.
