Product Showcase CPU cooling

Let's call this the front-side. Here you can see the pump (left). The entire unit is protected against resonating noise with rubber inserts and what not. The right side can be opened up, so you can access the reservoir/loop and refill if needed.
 

Overall the design is kept simple, and simply always seems to get the job done for some reason. No advanced software control or LEDs, just a properly nice build radiator with a built-in reservoir, pump totally pre-filled and connected.
 

If you mount the assembly in the front of the case instead of the top, you could still refill it as this "top" side offers access as well. You connect one CPU fan header on the motherboard, and lead it to the two-pin connector. 
 

To the right, you can see a horizontal connector. This is used for pump power and you connect that wire to a PSU SATA power connector. Once activated a LED light will light up. So there are just two wires that lead to the reservoir, easy for cable routing and hiding cables, and not a spaghetti flurry of cables leading out of the cooling block.
