Well if you actually look at molex connectors, youll realize that they arent that sturdy to hold up to changing them alot of times. I would have to recomment a fingerboard. Each panel gets its own fingerboard (1-3 bucks each) and then you need one connector in your cabinet (I hear these are a little more pricey). Then, you just pull out the connector and insert a new one. If you do it fancy enough, you can probably route a tunnel in your panel, put your wires in there, and cover it with a wood filler so nobody sees your wires. Then on the far end, you route a space for your connector to slide into......I just got an idea! Nobody will see my wiring!
