With all of the drives in place and things cleared out of the way, we can now add the Mini-ITX motherboard to the case, followed by the primary (ATX) motherboard.

The Mini-ITX sits on the right side of the case below the PSU for the primary system, and I will use the main PSU to power the HDD for the Mini-ITX to minimize cable clutter. Here is a picture before we add the Mini-ITX system. You can also see that there are holes in the floor of the case which are large enough to allow for the routing of tubing if you wanted to install a water cooling system. Plus the case comes with some mounting holes for the pump and other water cooling equipment.

Here you see the secondary system installed and ready to have the cables hooked up.

Placing the BFG PSU in the case, we can see how much space both of these take up. It's really not all that much, as all of this is behind the primary motherboard. There's still a more than 30cm of free space over the PSU.

I've fed the cable for the secondary system's hard drive around the motherboard tray and up to the hard drive on the other side. For the keyboard, mouse, and video cables, I had to punch out the larger hole in the back of the case and put a protective edging on it. Below the hole I punched out, you can see where you could punch out other holes for water cooling tubes.

Here is the other side of the motherboard tray, before installing the primary computer system. Note the front intake fan that blows air across the motherboard.

Finally, the system is in place. Let's look at how we got here:

Just a few of the things we plugged into the motherboard. I took the cables from the front ports and ran them down the back of the case. The cables are long enough to reach and tie down with ease.

These are the cables for the 2 USB ports and the Firewire port.

Also, the HD Audio cable, there is also an eSATA cable as well (not shown).

Once the screws are removed you can slide the bar forward to unlock the drive bay.

When I moved to installing the video card, I found that the case design has it held down by a clip. It doesn't stop the card from wiggling back and forth, but it does do a good job of holding it in place. Card creep might occur, but I don't think it would be any more likely with this system than with screws. I did have to push it down over the backplate to make it fit.

If your computer(s) support tamper switches, the TX comes with them preinstalled on the door frames, ready to plug into your computer.
