NOTES:

• HDD Indicator LED only lights up when the system is powered on and disabled when the system boots, the connector is on the IO card, am unsure how to correct this
• Turbo LED does not light on but the system is in full turbo mode
• Overdrive CPUs get very hot, I have mounted a fan on the heatsink with sealed wiring in order to not damage the heatsink with screws, the buyer may want to modify this to their liking
• Case fan and CPU fan are high RPM and very loud, this ensures the system is properly vented
• Battery compartment is mounted to the empty motherboard space with cable ties in order not to damage the case with glue or tape, the BIOS requires 6 Volts (4x 1.5V batteries)
