Installing other cards is very similar to what was done for the graphics card; remove the back expansion plate and insert the card into the proper slot. For my set-up I needed to install the sound card that came along with the ASUS Striker Motherboard. A great addition for the future will be another graphics card and possibly a Phys-X card.
Step 12: Connect Drives & cables to motherboard
The biggest challenge I found was trying to make sense of how to organize all of the cables. Connecting the CD-ROM, Heatsink/CPU fan, Hard Drives and everything else is quite simple. The motherboard was labeled very nice and connecting them was straightforward. One tip when hooking everything up is to try to keep the calbes from getting tangled up too much. This is where the plastic ties came in handy, I also used some electral tape to tape some cables down so there were out of the way in case I need to get back in to add or change something.
Step 13: Connect Perperihals
Connecting the keyboard and mouse is the next logical step prior to powering up the PC for the first time. I would recommend not closing up the case just yet as you may need to make some minor tweaks or change some connections to make sure your BIOS is working right.
Step 14: Setup BIOS
We're not ready to fire up your PC for the first time. Setting up the BIOS shouldn't be hard and in most cases if you've connected everything correctly you most likely won't need to do anything. Simply Turn the PC on and wait for the BIOS startup messages to appear. I'd recommend inserting your Operating System Disk at this time since you'll probably get a OS not found error. I did have a minor issue with my BIOS setup; since I'm using an external Fan controller the CPU fan was not connected to the motherboard and this it was throwing an error stating that the CPU fan speed was too low (it displayde 0 RPM) I reconnected the CPU fan to the motherboard and it started up without issues the second time.
Step 15: Organize Cables & Close Case
Before closing up the case, it's good to make sure there are no loose cables floating around that could interfere with fans or anything else. Plastic ties and some electral tape or fasteners should do the trick here.
Step 16: Connect Remaining Perperihals
Once everything is closed up, connecting speakers, printers and any other externam perperihals can be done at this point. It's good to have everything connected so you can get all the drivers loaded as you're installing the operating system in the next step.
Step 17: Finish Installing Operating System
See it up & running
At this point you're at the home stretch, installing the Operating System is very easy just insert the CD-ROM and follow the onscreen installation and setup wizard as you are prompted.
Step 18: Install Drivers (if necessary)
Microsoft tries to include a comprehensive list of drivers with Windows but it's not always the case. In this step go ahead and install any missing drivers so everything is functioning and recognized correctly by the OS.
Step 19: Install the Games
Now's the time to throw in that first game you've been dying to play, install and enjoy!
