Do you have any idea how expensive a solid block of copper that big is?
Would you even notice, after buying the ram and storage?
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.
If this were in an enclosure, would it cause the PCB to bow over time?
Yes but you save on manufacturing.
Copper isn't that bad. It's not cheap exactly, but it's probably going to cost what an expensive CPU cooler already would.
Despite the cost, it's damn heavy.
and just stupid. Cooling fins of aluminum work better.
11 euro per kilogram
