Hi Boehrsi,
The Zipang could fit, but we had issues with Asus Striker Extreme. I heard it has veeeeeery high RMA Rate, like no other. The RMA is something I don't care about, but they had at least 2 versions, one was OK with Andy Samurai Master and 1 not. Zipang is a bit better with compatibility compared to Andy Samurai Master, but I don't have a Striker Extreme around. SO my assumption is, that it will work with a chance of 60%. Not much as you can see...but I want to be rather safe, don't want you to be mad at Scythe
OC should work with Zipang, did not test, but will test it this week.
Cheers,
Shinigami
