I bought one of these, with the full 64GB of RAM. So far it's been a fun machine to play with. In UEFI mode I can install Fedora 42 with essentially zero issues (it tells you that the bootloader didn't install but actually it did and works fine), which is quite smooth for ARM. It will be nice to see the CPU clusters, GPU/NPU drivers, and various PCIe snags worked out, but I really like what it has at this price point (assuming you're not in the US).
