3070 and 3040 motherboard are both proprietary and nonstandard in form factor.  the 3040 case works only with 3040 oem board, not 3070.  the psu pinouts are different too. [IMAGE] 3070 sff [IMAGE] 3040 tower
Hey everybody! Can I swap my 3070 SFF motherboard into my 3040 Tower motherboard? I wanna put in my 3070 motherboard to my 3040 Tower case, and vice versa. I would like to use both of pc's.  Thank you for the answer!
