You may consider assembling the computer outside the case first on a wooden breadboard or the like. You can start with the CPU, HSF, graphics solution (if not on-board) with monitor, and 1 stick of RAM. No drives. You should see the boot process make it through POST, then halt when it cannot find a boot drive. If that works, then verify your standoffs, and install the motherboard in the case with your full complement of RAM.
I did the outside test, like you say. It looks good.
Well, first, triple check to ensure you have not installed more standoffs in the case than the motherboard needs. Since cases are designed to support 1000s of motherboards, they typically have more mounting holes than any given motherboard requires. So you MUST ensure you don't have an extra standoff under the board that may short out the board (and anything plugged into it).
The case came with this paper template, I took it and lined it up with the MoBo. Then put it in the case, and only installed those marked. The case has no extra post and all the post has align and screw down the MoBo. I feel very good about the post issue.
This does raise another question. The screws that hold the MoBo down are they special, like big round. Besides holding down the MoBo, do they serve another purpose?
The holes for the MoBo spots of solder that the screws will contact. I assume that this is for assuring low voltage ground. I used the 2nd row, 2nd type screw from the picture. I have seen some screw, (in the install kit, the kind with pliers and screw drivers) have fiber washers.
As for your side window, while I am not a fan of fancy cases (I think they should sit quietly and discreetly off to the side and NOT draw attention to themselves - since I prefer to pay attention to what's on my monitors) side windows are nice for conducting REQUIRED monthly inspections for dust build-up an fan operation without having to tear-down the computer and pop open the case. And too that, as I mentioned several times in your other thread, a case with removable, washable, air filters minimizes the number of times you will need to tear-down and clean the interior, but sadly, that CM case does not have them. So not a case I would get, but at least it does offer lots of cooling options.
Tell ya the truth, that is what I was thinking too. The front fan has a foam screen on the grill, like you suggested. Fresh air comes in the front, and over the MoBo. The exhaust fans will remove more than the incoming fan. This will be plenty of air exchange. Being able to see thru the window will give me heads up on dirt, bad case fans, or bad CPU fans. I am deaf, so the visual will help.
