Once all the peripheral devices were mounted, I installed the motherboard (with the CPU, CPU cooler, and RAM already inserted). You may prefer to install the motherboard before you mount the optical drive cage but I was able to easily angle and dip the motherboard under the installed optical drives and then slide it back into position on the mounting standoffs. The board lined up perfectly and the expansion cards also lined up perfectly with the rear slot openings. Again, the CW01 is not a tool-less enclosure and all the expansion cards are secured with machine screws, which is just fine by me.
Here are a few more pictures of the CW01 with all the major components installed.
Routing all the various cables proved to be relatively easy as there is a lot of space in front of the power supply and around the HDD cage to work. Be sure to keep things neat and not block airflow to critical components.
Audio Cable Adapter
The front panel audio jack cable is terminated with a special Sound Blaster Live!/Audigy/X-Fi connector that plugs right into the header on top of a Creative sound card. If you are not using a Creative sound card, the supplied adapter will allow the audio cable to be plugged into an AC97 or HD audio (Azalia) motherboard header.
For anyone interested in rack mounting their CW01 HTPC case, SilverStone offers a very nice rack mount kit. Two steel extension brackets securely bolt onto both sides of the enclosure and feature large, solid aluminum handles. They are available in either black or silver.
