I just received my i3 1215u box today from the Topton Ali Store. It's exactly the CWWK model, even the logo in the BIOS is the CWWK logo, and BIOS version is the same as fta box.
I used a pair of DDR4 3200 Crucial Sodim (Ref CT16G4SFRA32A) and a 1TB SN570 NVMe drive and start to play with it. Memtest86 is quite happy with the RAM, and during the test CPU temperature went only up to 58 °C.
I had some hard time installing Proxmox VE, as the screen switch to black screen pretty quiclky during the process. After searching a bit, there are two options, using a USB-C screen connection, or installing from the 7.1-2 iso (need to find a mirror that still have it) and updating to 7.4 after installation (as well as Kernel 6.2). Not a big deal, but that may help people who have the same issue.
