Thanks for tuning in to our last part of our LAN box project. I hope you read out first and second part to get the low down on what we have done so far. We have finally put the finishing touches on our Lian Li Mini-30 case and I have to say, this is one sweet box to use if your gonna carry it to a LAN party.
We left off last time having put together the neon and the grills. What we are left with is the addition of a bay bus and the internal system. Let's start off with the installation of the bay bus.
For our LAN box, we utilize the PCMods.com's circuit board bay bus. It has 4 switches, and 4 leds. It varies between 12v/off and a slower speed, which I am assuming is 7V. Each switch is rated at 6W per switch, so each should be more than sufficient for your basic 12V fan. The LED above each switch will turn red once it is at full speed, off when it is off, and green when its is at the lowest setting.
To start off, we followed the instructions that came with the Baybus. You're going to need a drill to get the holes cut using their template. We won't go into details on that, since this isn't a Bay Bus review. Here is what you should have after drilling out the 8 holes necessary for the leds and switches:
That is one of the aluminum bay covers from the Lian Li. If you do plan on using this case like we did, just make sure you go slow. The aluminum material cuts very easily, I'm sure you don't want to scratch that fine finish.
The above picture's top row is for the LEDs to show through. Each LED hole comes with a plastic bezel to hold it with. Makes it look neater, a nice touch by the fellas at PCmods.com.
Our next step involves figuring out where and what fans we are planning to control. Since the bay bus uses bare leads from the fans (red/black), we are going to have to make sure to strip any kind of connector that the fans may have.
Our first fan is the top blow hole we made in Part 2 of this guide. As you can see, there is a red and a black wire protruding from the fan. We will be using these to control this fan from our Bay Bus.
The next set of fans that we will control, are the 2 80mm fans that are located in the front. These are Adda 80mms that came with the case. The fans are attached to a fan controller made by Lian Li.
This tiny circuit in the front, is Lian Li's own tiny version of a bay bus in a way. There is an option to set the fan speed to high, medium and low. This is in effect, utilizing the same concept of what the bay bus is doing, by limited the voltage, the speeds of the fans will slow down. This in turn lowers the noise of the fan, but also weakens the fans ability to suck and push air through the case.
Those are the two wires that we stripped to prepare them to use on the Bay Bus. You can get a pair of professional wire strippers to do the job, but if you are ghetto like us, use your teeth. Those ivories are very powerful.
To make room and have the wire as close to the Bay Bus as possible, we strung the wires from the top blow hole fan and the two bottom fans through this hole in the bottom 5 1/4 drive bay. Since we are going to be using a DVD/CD-RW, we had an extra bay to use, that was perfect to install the Bay Bus.
The Bay Bus has 4 spots for 4 fan devices. Each spot contains 2 screw down terminals for the red (12V) and the black (ground) wires that come from the fans. Try and obtain a small flat headed screw driver, its a lot easier to work with those terminals using this small tool.
After successfully screwing in the wires, they should be snug within the terminals. Don't pull too hard though, they are tiny wires.
Take the washers from the switches and screw them in tight. The Bay Bus should look something like this:
This is a preliminary look at what the Bay Bus is going to look like in our LAN box. Not too shabby if I do say so myself! : )
