    is removing a pci plate at the back of a pc a bad idea? if so why? i'm
    asking this question rather naively but i do remember seeing somewhere
    that computers (in this case an evo d530) are designed with the vents
    and fans to maximize air flow and actually removing a plate can impede
    this.

    If a case has fans inside blowing air both in and others blowing hot air out
    of the case, then yes, removing a pci plate would impact performance

    Careful engineering (which can't be assumed for all manufacturers, of
    course) usually includes putting the hot spots in the path of the
    moving air.
    If you open the case in another location, you have changed the path of
    the moving air -- even if the flow is higher, it will be higher in a
    different location, and maybe too far from the hotter devices or chips.

    So while your basic idea is meaningful, it can still reduce the
    effectiveness of the airflow.

    If you can figure out which spots are the hottest, and need the most
    cooling (the most high-clocked chips and the tightest chip designs,
    plus the power distribution) you can probably figure out some ways to
    improve the flow. It just isn't as easy as making more opening.
