    I am going to modify my MP 5,1 case for various reasons. I need to basically externalize the power switch.

    Apparently the switch just plugs into the front panel circuit.


    Does anyone know where I can either get a replacement power switch or just get the little plug there so I can throw in a momentary switch?

    Based on the pictures I think it's about 3.7mm (4?)

    My thought: cut wires extending from existing plug, solder appropriate gauge extension wires on as needed, and attach to your favorite replacement switch.

    The connector itself is probably a molex part, you'll just have to dig around online to find the number and then source a replacement. Taobao or eBay are a good start but I found its actually harder (though possible) to find the wires pre-pinned on their own than the connector itself. Maybe if you can find a cheap premade part that includes the correct wires and connector it might be easier although more costly...

    This is the only permitted replacement switch by the way:

    Nice replacement :)

    Yes I think I may have found a replacement plug for it but it'd suck to disassemble the whole thing only to find out I'm wrong. I may just buy a replacement switch. Someone's already posted the pinout on another forum.
