3. Mounting the Drives
Even if you've figured out how to get the faceplates off the front of the case, it's not necessarily a victory. Most good-quality cases have a secondary metal faceplate behind the case's fa
For the P180, these metal plates twist along the horizontal axis and are held in place by two small tabs, one on each side. It doesn't take much force at all to twist these plates back and forth until the tabs break. Don't worry if the plates fall into the case. They drop down to a platform at the bottom of the 5.25-in. bays and you can retrieve them when you're done.
4. Primary Wiring
With the motherboard and drives installed, it's time for the primary wiring session. This includes connecting all of the cables routed from any top- or front-mounted ports (usually USB, FireWire and audio) as well as the front panel controls and LEDs (power-on, reset, power-on light, hard drive activity light and so on).
The front panel wiring (the multicolor ribbon cable in the picture) requires that you refer to the motherboard manual to learn which wires mount to which pins. I usually just print out that particular page from the electronic version of the manual (often found on the install CD or the vendor's Web site) so I'm only fumbling with a single sheet of paper. A good flashlight or task light is a must because you're actually sticking your hand and head into the case to do the job and you're probably going to block most of your ambient light.
5. Mounting the Power Supply
This is the moment when you meet the worst grief of the entire build. In the case, my P180 not only had the standard mounting screw positions at the back of the case, but it also had a cage for the PSU that needed to be removed first.
Once you've removed the cage and placed it on top of the PSU, start routing the power cables up into the center of the case. This is impossible to do with the power supply installed.
With the cables partially routed into the case, you can start jiggling the power supply into place while pulling more of the cable through the hole in the partition. It's not really that difficult to do if you keep your wits about you and your eyes on how the PSU is sliding into place. For the P180, I needed to re-install the four screws at the bottom of the four corners of the cage plus the four screws that hold the power supply to the back panel.
(In the picture, it looks like that main trunk of power supply cables is right against the lower fan hidden by the black mount. It's not. The fan itself is recessed three-quarters of an inch further forward, and that's more than enough breathing room.)
6. Drive Cables
One of the great things about the P180 case is that I could remove both banks of 3.5-in. drive bays during the assembly. If you have ham-hands like mine, removing the upper bay can give you better access to the IDE connector (the blue one is the primary on this motherboard) so you can connect your PATA drives.
