Reddit mentions of SilverStone Technology 2.4G Wireless Remote Computer Power/Reset Switch Components RL-ES01-PCIE, Silver

Splicing the cables back together is probably your best bet, but failing that, you could get something like this:

Sorry it's not a mech-based solution, but how about using a wireless remote just for power?

Leave that fob out on your desk or something and voila!

Silverstone is the best. I've had a few cases by them and they seem to be the only mfg who really innovates and thoroughly engineers their ideas to something that really works.

Booting on controller input is something PCs really lack right now. That and hdmi cec. I know, I've been dealing with the cec thing. That may change eventually, but for now I think you're best just leaving it on and letting Windows restart when it updates overnight.

*Edit: hang on, check out this pc power remote: http://www.amazon.com/gp/aw/d/B01879FI1Q/

You absolutely can boot into steam big picture mode, though. See here: http://www.howtogeek.com/233911/how-to-make-your-windows-gaming-pc-automatically-boot-to-big-picture-mode-like-a-steam-machine/

Personally, I don't mind using a keyboard and mouse on the couch. I just have a backlit wireless keyboard and wireless mouse. I used to use them on a board across my lap, but now I just have a rigid mouse pad alongside me and hold the keyboard in my lap.

This happened to me on my old case. I double-sided-taped one of these over the power and reset button.

Or better yet, disconnect the case buttons and install a remote switch.

EDIT: about the power button thing, I don't know her handicap but there are wireless ones.

Don't buy those cheap case fans.

$599 for a GTX 1060 is a bit much... it should cost ~$250. Get a GTX 1080 if you have that kind of budget. If she doesn't need anything crazy, a GTX 1050Ti is probably fine.

The stock cpu cooler is enough.

You didn't mention the monitor/keyboard/mouse/speakers?

Alt. black/red theme: (CPU is a bit overkill but will last for a long time)
