Project completion
final update from me, over the last few days i have had time to take a real good crack at this project and finally get this finished. As stated above the origional idea was to have the lights controlled in an eexternal box. However, wiring up the pins for the connections was extremely messy so i opted to find a way to adapt the panel i had already cut into the existing computer.
The best way i found was to let it use up two Disk drive bays , this only meant shaving of 35mm off of each side of the panel and fixing it into the bay. To fix it into the bay i decided to destroy an old CD driv and use a hot glue gun to stick the faceplate to the drive's chassis.
because i had already precut the majority of the wires (or had come pre-assembled) i did some re-arrangment to make sure everything could get connected up - this was the hardest part as i had to work with the panel half into the computer with my hands stuck into a pile of cabling.
THe main fan switch had a built in LED so i created an extra lead to connect to the computer case to act a s a ground. Apart from this all the necassery connections were made to a molex connection supplying 12v and ground.
To get the coloured lights to show around the computer effectivly i created four sets of lights each with a row of a particular colour LED with their matching resistors. In hindsight id look at using pre made cables such as USB cables to reduce the mess of cabling now in the computer. However, i really do like the flexibility of having multiple boards (you can also add more on later on if needed).
My major suggestions if you planned to do this yourself would be to use sets of 3 LED's in series with a rating of 5000 mcd or higher. I personally used this rating for all but the white LED's of which there where two producing 11000mcd. This meant that it washes the computer in allot of light - useful for looking into the case and future modding
.
Bellow are the pictures of the final build including the last building stages and the taking apart of the CD drive. My best piece of advice would be to forget about having an external control for this as it just overcomplicates things and introduces so many chances for dodgy connections - its just not worth it. I would also like to remind any thinking of doing this that i take no responsibility for any accidents or injuries that may be incurred from following any content within this thread. All parts of this project is designed around a 12v rail capable of producing 60A worth of power, which if not properly protected by can cause serious injury or even death.
Hoep you enjoy the pics!
