A friend gave me her old ASUS M4A785T-M mobo with an AMD cpu and I got a Rosewill Line-M mini tower for it. It would fit perfectly into the case except this COM1 port in one corner is bumping against the case's metal drive slots. I don't think I'll have any need for this COM1 port. I want to get this build put together today and not have to wait for another case. Would it be OK if I just snipped the top plastic part of the port off to allow the mobo to slip in place or would that be a bad idea? Thanks.
