In compatible parts.
Setting up a NAS from old hardware is challenging. You’re looking for a Micro ATX or Mini ITX board that fits your i5 7400, but you also need a compatible CPU for your H370M DS3H. Since you upgraded both the CPU and motherboard together, you might have assumed the new board would work with your old parts. However, compatibility isn’t guaranteed. There are no direct workarounds to make an i5 7400 run on a 300-series 1151 board without significant modifications or compromises. You may need to consider alternative solutions like using a different CPU model or exploring used components that better match your requirements.
I understand, I'm actually using something similar. For you, the best choice would likely be a budget Athlon 3000G or 2200GE paired with a budget B450 model such as the B450 DS3H.
