The stainless steel G1/8 and G1/4 arrived and they are chonky! Here are some quick photos comparing a G1/8 to the Modultra supplied Nickel plated brass plug and a G1/4 to a Bitspower Matt Black plug. Note the length and that the thread only starts 1/4 of that length for the stainless steel plugs.
There is not enough depth to use them and not enough thread to secure them well even if I shortened them.
Summary: Modultra's one is pretty good. Just debating whether to strip the nickel..
I'm ordering a G1/8 to G1/4 from Bitspower and will report back on fitment.
I need some help remembering this > the prototypes had acrylic bars with kapton tape on them. The tape is about 0.2mm and I removed them thinking they were just acrylic film protectors... Is the cold plate zeroed with the tape or is it set to be concave? I will be lapping the cold plate for direct die testing.
