 Have the Phanteks P400a.  Never have drilled through a PC case before.  What is the best bit for it and do you need to worry about filings falling/flying into the Motherboard/PCBs?  Thanks.

    I would say a new sharp bit would be a good start.
    You can hit it where you want to drill with a prick-punch so it's dimpled to help stop bit from walking.
    Go slow with the bit, not full speed.
    Also you can use duct tape on both sides and drill through so the metal chips do not fall on the board.
    The chips will stick to the tape. Hold a piece of paper or cardboard under where drilling to catch the chips too.

    You should use HSS Hi-Molybdenum bits and you can find them at your local Home Depot/Lowes and, while there, pick up a small can of cutting oil.  If you can’t get cutting oil, any light oil you have laying around will suffice.
     
    Mark the spot you want to drill and use a center punch.  Start with a bit half the size you want for the hole to make a pilot hole.  Dip the end of the bit in the oil, drill the hole slowly.  As mentioned above, take your time and don’t overheat the bit.  Then move to the size bit you want for the hole and repeat.
     
    The tape trick works, but with the tape, you can use your shop vac at the same time to catch anything flying off.  You are probably going to have to file some rough edges at the exit hole.
     
    Having done mods on cases and other things, I personally would not do this with the anything in the case.  I tend to try to error on the side of caution since learning the hard way.
     
    Hope this is helpful.

    Any PC case on earth that has steel, will be mild steel... also known as chineseium.  Its a step above aluminum (and even that is debatable)  Any drill bit will work.  But as others have mentioned newer drill bits will work better than dull ones, as well as a punch to prevent the bit from walking.  As for chips using a shop vac while drilling will help, but nothing beats gravity.  Ensure that whatever you are drilling is below the motherboard so it doesnt fall down, so rotate the case accordingly.  Best practice will always be not to mod a case with a motherboard in it.  
     
    If the hole is larger, try a step bit.  They are many bits in 1.  I know it's scary to drill into a case for the first time, but once you get your feet wet, you will look back and laugh at this thread.  Good luck!

    Also, once you start, you'll start thinking and tinkering with other mods for your cases.  If you don't already have them, the next thing you know you'll be looking at Dremel tools and drill presses.

    Tin snips do wonders on my cases!
     
    Also knowing what size hole he needs will make a difference on what drill bit to use.
    If you need a 3/4 in hole for a tubbing use a step drill with the tape and a vacuum.
    Or if you know someone with a hole knock out tool. Maybe an electrician friend may have one.
    A bigger hole would use a hole saw or tin snips.
    Auto parts store has edge guard to cover the edge and make it safe and look good.

    Wow those Hi-Molybdenum bits don't come cheap, but guessing they're worth it.
     
    Thanks for all the tips and advice.  A plan is in action.
