With the motherboard installed in the case and everything up and running, this machine is a riot of light. The Ballistix DIMMs include red LEDs (we didn't notice that when specifying them), and right next to them is a pair of seven-segment diagnostic panels. Cables are kept to a minimum thanks to the Scythe Stronger PSU's plug-in cable sets, so you only install as many sets as you need; this avoids having lots of redundant cabling to tidy away and potentially block the airflow. The green reflections off the top of the PSU casing will be explained later. One thing this photo doesn't show is that the fan on the Sweex-built graphics card was the noisiest component by far.
Zooming in shows the diagnostic panels, the system battery, the pair of DDR3 DIMMs (complete with LEDs) and the power and reset switches that Intel has mounted on the board. This makes benchtesting much easier — helping you to test over-clocking before full installation, should that prove necessary. Just above the battery, you can also see the cable plugged into the front fan header, while over on the left is a corner of the heatsink and fan assembly.
Lower down the board, below the graphics card whose fan and heatsink assemble occupy the top half of this image, are seven green LEDs mounted directly on the board. As you can see from the logos, they provide POST diagnostics (from right to left): CPU, memory, video, optional ROM, USB, hard disk and OS start. If any of these devices fails, the LED glows red and a beep sequence lets you know what the problem is. Also in this shot are, on the right, the front panel indicator headers (as fiddly as they always are) and on the left, unused auxiliary fan and S/PDIF headers.
