My motherboard model is a Lubrin 82F2 motherboard. It'd an H270 board. I wanted to swap cases but turns out, the motherboard mounting holes don't match up with the standoffs of the NZXT H500.
You have a non standard motherboard.
Are the standoffs on the H500 removable?
Are there enough places remaining to be able to support the motherboard without bending?
Not all holes need to be filled
