I can't find it anywhere. I have the ASUS Z10PE10-D8 ws board so I assume it doesn't support the SFF-8639 hardware interface to the MOBO. Maybe theirs an adapter? I really would rather have 2.5 form factor for thermal management reasons. The PCIe AIC uses up a slot and is neat two heat creating Titans. Plus I have fans up front for the 2.5 form. I asked ASUS about bios support for NVMe so we can boot off this drive and they acted like I had two heads lol. I assume they know about this?
