Acer G3-605 atx motherboard?

[IMadeYouReadThis]

I own a Acer G3-605 prebuild computer and i wanted to buy a new case for future upgrades and better air cooling.
I took of the sidepanel-window and then i discovere that the mounting holes on the motherboard are in very strange places, also, it has a 12 pin main power connector.

I don't know what to do becuse the mounting holes are not placed like on a ATX or mATX.

If this is your motherboard and it has the same mounting holes as yours

Then I would say it is a micro-ATX form factor. Some of the holes are just not there. Here is the mounting hole locations for ATX, micro-ATX and Flex ATX. Not all mounting holes are required by the standard.

And yes, 12-pin power, isn't Acer wonderful. Particular to them.
