Looks nice. Why they don’t sell PCs with cooling like that? What are the downsides?
Do you have any idea how expensive a solid block of copper that big is?
If that block is roughly 4.5cm x 4.5cm x 25cm then the volume of it is about 500cm³ which translates to 4.5kg of copper. At 11€/kg that makes about 50 euros.
Cheaper than some noctua coolers.
