Besides from Other World Computing, has anyone purchased a third party 64GB upgrade kit for their 2018 Mac mini? TransIntl doesn't appear to offer 2018 Mac mini memory yet. Crucial doesn't sell 64GB kits. Data Memory Systems cryptically lists the price for the appropriate 32GB SODIMMs as "call". I suppose I will have to do just that, but I'm curious to see if anyone else has maxed out their new Mac minis on their own so far.
