I have never built a PC before, so I'm a complet newb. I am at the stage where I'm trying to match up the motherboard to the case, neither of which is chosen at this point.
Say I'm looking for a MiniITX motherboard, so I choose a case that supports MiniITX. When I look at pictures of the motherboard's rear I/O panels, the cutouts on the MinITX case don't necessarily perfectly match the rear I/O panel of the motherboard. Does each motherboard ship with its own rear I/O plate with the appropriate cutouts?
The motherboard comes with an aluminium cut-off for the I/O ports, the case actually only have a big square gap in it. If you have doubts, just post your choices and people will let you know if they will work together.
