As for the inside Lighting, though I read that Bitfenix LED Strips are more reliable than the LED strips you can get from car accessories shops, I will take my chances. Cars run on 12V which is the same as what can be provided from the PSU, I feel there is no issue there.

This is the circuit diagram for the pump bypass I am planning to make. I have designed this circuit as simple as I can to minimize faults. I initially wanted to design the circuit with over voltage and current protection, along with an adjustable voltage regulator to control the pump+fans, but as my lecturer used to say, don't make it so complicated.
I am going to rely on the ASUS Fan Xpert 2 for fan and pump controls.
I have seen and watched how water is filled into the watercooling system by shorting the PSU 'on wire' with 'ground' temporarily to cycle the water in from reservoir to loop. I do not want to pull out the socket from my MB to PSU every time I want to fill water into the loop. There is also another way which is to pull the pump power socket out and link it to an external power source. I agree with the method of using external power source, but once I have already done my cable management, it might be hard to unplugging my pump's molex power connector.
What the circuit does is simple, once I connect an external power supply to the port I made at the front panel the 2 relays activate in order to disconnect the PWM+TACH pins (My Pump has PWM. Model: MCP35X) and divert pump power from PSU to external power. With the help of the switch I made at the front panel, I can control the pump at will. I have not decided if I want to use a 10k variable resistor to control the pump, as its inefficient.
Relays, Switches, Resistors and Connectors. I guess it cant be any simpler than this.

If you have any suggestions, comments or a better alternative, please tell me:) I know this circuit can be improved more:)
