micro ATX and it doesn’t look like the holes will align

Ah OK. Best thing to do is just give it a go when you go get the board but make sure there’s nothing shorting the back of the board etc.

Find out what case model it is and you can check if a standard board fits. Dell sometimes has weird boards but I quickly Googled your board and it says it is a micro ATX board so the case should fit.

Is it a Dell dimension 4600 or something like that?

How bizarre.

I’ll keep this in mind if I come across this bug.
