I did a search and didn't come across anything. Has anyone come across some place that sells those plug n play side panel fan contacts that Thermaltake uses on the Element G?
No but I bet you could make something similar... it's just having 2 metal contacts that are in the right place, so when you push the panel back on they are touching so the fan will spin.
If you felt like it you could have 3 for RPM too... just run wires to each of these pads, set them the right distance apart / glue/attach them in place and wallah.
