I did find one on eBay, but the seller is away. If you think that's the way to go I'll order it and find another buyer for the Morpheus II. They seem to be selling for more anyway, so I may come out ahead on this deal. I can see that it's much lighter by almost half.
EDIT: OK, so I can't preorder it. I do have an RTX A2000 12GB on the way, so I'll just wait. I may put in the order for the copper plate too.
EDIT #2: I just realized that I bought the 12GB version and yours is the 6GB. I tried finding a teardown video or picture and can only find the 6GB and I'm wondering if there's a difference in the PCB layout that would make your plate incompatible.
As a side note I came across these
copper memory plates that allege a 10C drop in temps for the memory. Think it's worth it?
