I use a BT60v2 wireless PCB, the solder version that is the one that supports the HHKB layout. I have it in a kbdfans d60 lite case. If you go for this option I have a zmk github repo to program the PCB
You can also get a QK60 v2 from querykeys. I don’t recommended the wireless version as the programming software is proprietary and is very limited
Love th hhkb layout too!
