Question M-ATX vs m-ATX motherboard

[EdwardR6]

What is the difference between M-ATX and m-ATX so far the only difference I see is the dimension.
If I try to install the m-ATX msi B450 Pro-VDH Max on a pc case where I use to have the M-ATX B150M Pro-VD will it be possible.

B450 motherboard: 24.4 cm x 24.4 cm.
B150motherboard: 23.5 cm x 18.0 cm.

If not any better suggestions for Ryzen 5 3600, ripjawsV 16gb ddr4 rams, msi gtx 1060 3gb?

Yes you should be able to fit the b450 in the same case. Cases are generally designed to be universal in peg locations for all types of board sizes.

The maximum size of an m-ATX board is 244 × 244 mm. Both those boards fit within the max, so the only difference in M-ATX and m-ATX is one capitalized the letter.

ADD: I'm pretty sure your plan is to replace the B150 board with a B450, which would work into the same case.
