Increase scenarios and double delete

Hey There

1 : I would like to know if its possible to increase scénario complexity , as we know computer parts have to be selected carrefuly .
I linked CPU with motherboard , then Cases with motherboard .
It does not work well because its showing motherboard compatible with cpu (not case ) AND motherboard compatible with Case (not cpu )

So it shoes ATX motherbord with Matx case and Intel motherboard with AMD cpu ..

2 : double delete
if customer delete item 1 , i would like it delete item 2 aswell

Exemple : I select processeur AMD as item 1 , AMD motherboard as item 2 .
If i decide change the processor from AMD to intel , the AMD motherboards stays .

Any way to link those 2 to remove if a componant is changed ?
