You can always use a simple way of attaching your waterblock to the cpu.
You will use the computer case as a fix point then then you assemble pressure with a screw, you will nead a mutter, a plate, and a screw
its quite simple, but you will nead to have something under your motherboard.
this is only theory, i do not knew if it will be a good solution.
