Having just upgraded my computer, I had a bunch of old components knocking around and thought I'd put them together. It was all going well, right up until I spotted the connector on the cable for the power button on the case (power/reset/led) isn't compatible with the motherboard.

So, the question is how to turn it on without the power button on the case?

Are there any alternative ways to turn it on, or even 'hot wire' it somehow? Otherwise, I'll be skip-diving for a new old case

The motherboard is an MSI Neo2 865Pe
The case is from a ten year old Dell Dimension XPS T700r
