Installing the Motherboard
Step 1. locate the screw package that came with the case and what your looking for are the motherboard standoffs.
These standoff screws are what is used to attach the Motherboard to the cases Motherboard plate.
Step. 3. On the Motherboard you want to locate the holes that the screws will pass through and into the standoffs.
Generally there are 8 or 9 of these holes and they are spread out over the surface of the Motherboard. You want to take the Motherboard and place it on the Motherboard plate.
There are a lot of screw holes on that plate and you want to line up and mark the holes that line up with the holes on the Motherboard.
Step 4. Next you want to take a standoff screw and screw it into each of the holes that you marked, once you finish doing that count the number of screws that you put in and the number of holes in the Motherboard to insure that you have the same totals.
Step 5. Before setting the Motherboard on the standoffs it may be a good idea to place the CPU into the CPU socket on the Motherboard as it would be easier to do this on a flat surface and not reaching inside the case to do it.
Also at this time you can apply the thermal compound, as shown in this tutorial.
Then attach the CPU heat sink. If the heat sink has thermal compound pre-applied then you won't need to add any.
Step 6. The back I/O panel needs to be installed before the Motherboard so at this time you would need to do that.
Step 7. Now you can set the Motherboard on the standoff screws and while lining up the screw holes you also have to make sure that the back I/O panel is lining up with the connectors that are on the Motherboard. The screws that are to be used for attaching the Motherboard are also included in the case package that the standoffs were in and one at a time begin to screw down the Motherboard.
Once all the screws are installed you are now done with the Motherboard instillation and you are ready to move on to the next phase of your build.
Working on the Motherboard and the installing of it can be awkward as you have to reach over the sides of the case to do this. Some cases have a removable motherboard tray which allows you to do all this on a flat surface and then slide it into the case. If you have a tall heat sink you would have to install the heat sink after the board is slid into the case since there isn't enough clearance for it.
Any time that you are working on the computer make sure that you connect the wrist strap or at least touch a wall switch plate to release any static electricity
