H80i fitting troubles

[SM125]

Tried today to fit a h80i on to a mATX board (not clever) and unsurprisingly it didn't fit.

Using the rear 120mm mount, once you have fit both fans and the radiator, the last fan almost covers the entire of the CPU giving no chance of fitting. I've tried the top mounts but to no avail.

My option I think is a new mobo, an ATX.

Can you confirm what I'm saying is true on this or recommend to me a full size atx board so I can install my h80i?

Socket is fm2+ and the CPU is a A10-6800k.

Would this suffice?

Forget a new motherboard, look into a new case for your build, one that'll give you the room you need to mount the rad. It isn't an issue of the motherboard, it's the case that's holding you back here

I would definitely get a new case to make sure it fits.

The case is fine, only just bought it too.
It's not huge but people have already fit h80i's in it.
The problem I'm having is because on the mATX boards, the CPU is very close to the left side, so when both fans and the rad are on the rear, they basically cover the CPU.

If I was to buy a new atx mobo, like the one above, would this or would this not fix my problem?
