>but air cooler heatsinks do not care what kind of case you use?
Oh yes they do. If you're gonna air cool a modern mid-range/high range CPU you're gonna need a pretty chunky one to even stand a chance.
That means a minimum of 150-160 mm of clearance above the motherboard. Might not sound like much but office PC's are always compact and horrible inside with terrible clearance and zero airflow.
>Höjd över moderkort = how much space it needs above mobo
Then you have to put into mind spacers behind the motherboard, cables and everything.
There's a reason modern PC cases are so bulky.
