Cooling using a heat sink as water block would this work?

I am thinking of using a heat sink as a water block. I would use a heat sink something like this as the heat sink. it would be fully enclosed in a clear plastic box and thread cut in the bottom of the base so the heat sink can be held in place using the holes in the motherboard. I am doing this because I think there would be a much more efficient heat transfer and save me some money buying a “real” water block. Would it work and is there any point in doing it?

I'm pretty sure someone has clad a Swiftech in plexy and make it into a waterblock.

I'll try and find pics

hmmm yes they look very nice!
i would be using a heat sink with fins as opposed to pins though.
cant seem to find anything on the performace of these blocks?

 

i never saw then end of that project - just checked it out on his site, and he put the acrylic in the pins BETWEEN then barbs, so the centre of the block has the least flow
