Thermaltake BigWater 735 Water cooling kit
 

The water block is impressive. It is quite heavy, having a solid copper base and chunky 3/8” barbs. The clear top looks really good, and there are blue LED’s powered by the fan connector on a motherboard fan-header. The base is round to accommodate any BTX form-factor motherboards that come out. It is very flat, and I can see that this is a quality CPU block. This is one of the changes from the original Bigwater kit, the CPU block supports all current CPU’s.
