Jonsbo N3 motherboard space

[Enquiries]

Hello I'm looking into moving my server into a itx case. I'm interested in the jonsbo N3. I noticed while it's an itx build. There's a bit more space under. I wanted to ask if you could measure from the top of an installed mother board, down to the wall of the case? I think I could squeeze an matx into the space while using a flex PSU.
