    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.

        If this were in an enclosure, would it cause the PCB to bow over time?

      Would you even notice, after buying the ram and storage?

      Yes but you save on manufacturing.

      Despite the cost, it’s damn heavy.

      Copper isn’t that bad. It’s not cheap exactly, but it’s probably going to cost what an expensive CPU cooler already would.

        Probably around $150 worth of copper there, but you’ll have to spend about twice that to get it because it comes in a larger size you’ll have to cut down.

        but a CPU cooler will work better because it is active.

          Well, yeah. Even a passive CPU cooler would probably work better.
