I am considering building a passive PC build (Monsterlabo), but I have a difficult time figuring out if there are any AMD mini-ITX mobos with the M.2 slot on the backside. https://www.monsterlabo.com/compatibility According to the website above, an AMD X470 mobo sort of fits, with tweaks, but I can't tell if the M.2 slot is usable or not. I guess I should contact them myself for that particular question. For the X470-I Gaming mini-ITX mobo, the compatibility lists states: *These motherboards are not compatible with standard fixture. They can be mounted by removing the mezzanine PCB (audio PCB) or by bending the CPU cooling and using a riser. Front NVMe slot can’t be used. For this assembly, please contact the team. If required, a dedicated fixture will be produced for these cards [Update: 11/03/2019]. Btw, removing the audio pcb sounds like removing audio, which sounds weird to me, I wonder what that really entails. I guess I should contanct them about, what that a custom fixture would even look like. Images showing the placement of the M.2 slot on the X470-I mobo: https://ibb.co/5GySkTy (shows the M.2 heatsink on top) https://ibb.co/4f2Crxd (shows the M.2 slot, but on an elevated level off the board) Disclaimer: I don't like to namedrop products, but I can't help but sometimes being a little excited. Having said that, I wonder where the I/O plate connectors are on the Monsterlabo, if the mobo itself is vertical, and not having its I/O plate out towards any of the sides. :| Edit: Hm, they are selling cables that appear to fit the custom back plate, so maybe these cables are supposed to just connect to the mobo, and feed the other backplate. Edit: Ah, so, it looks like a regular PSU (ATX) will fit, but can't be used together with the 120mm fan. So, a smaller PSU like Corsair SF600 has to be used if also wanting the 120mm fan installed near the bottom. ALSO, their off site forum news announced very rencently that there will be big news soon. So, I will hold my purchase until I get to learn what that is, even if that means this is some future product, I would like to know in advance.
