I have a full Talos II (eary bird, Blackbird and Talos™ II Lite did not exist back then) that I baught for a quite cheap price.
Since I do not plan to add a second POWER9 CPU and a Blackbird with SATA and HDMI is better for my use case, I now think of selling my Talos II.
My system uses a SuperMicro SC732i-500B, a first generation 4-core IBM POWER9 CPU and has 16GB of RAM.
I live in Germany and accept cash payments in Euro. I also have a bank account that supports US Dollar.
