As I mentioned, the motherboard is removable, so the first step is to add the risers and thumb screws to install the motherboard. Once my DFI was in place, you can see the wire management hole at the bottom of the board has very good placement, while the other hole is designed to use with larger server style motherboards, or to tie up loose SATA cables.
Before I set the CPU cooler, I thought I would show just how large the hole is in the tray. This allows you to just pull the rear panel and grab the back plate.
Once the CPU cooler was installed, I went ahead and did most of the chassis wiring so it is clean and out of the way for me to install the power supply. You can also tell now just how tidy the wire management hole beneath the motherboard is once connected.
As I mentioned earlier, the included wiring is plenty long enough to get the job done. Gently pulling the wires back through the hole, then running them through the wire management clamp doesn't exactly hide them, but does a good job of cleaning up what has to show.
There are a couple of key points to discuss here. First, the way the front panel is held into place. It uses four of the snap in clips, two of which you can see here in the top corners. Gentle pulling on the panel releases the grip in the clips. Second is the three speed fan controller switch that controls the dual 140mm intake fans. Last but not least is the stealth drive cover for an optical drive. This leaves the front clean and smooth in appearance when the build is completed. The doors top panel is spring loaded to allow the drawer to open, and the button aligns nicely with my DVD drive.
To install an optical drive you must first remove two screws so you can get the cover out of the way. Release the appropriate screw-less drive lock, and slide in your favorite drive. Locking it into position is as simple as clicking the side bar back into the locked position. If the drive is aligned correctly, very little effort is needed to lock it in. I wanted to also point out something I don't remember seeing up to this point, and that is the HDD activity and system power LED's. Ingeniously, Lian Li installs then to the front of the chassis and the front panel of the PC-B70 is wireless for reasons I'm about to address.
Aside from the wireless nature of the front panel come in handy to just set to the side for access to your drives being nice, I found a second reason to have this panel this way. I usually have to prop up a front panel for maintenance cleanings. Not here, you pull it off and set it somewhere safe while you pull the fan dust covers and clean them. I found a quick rinse and toweling it dry works nicely.
