Ask HN: Suggestions for hacking my laptop

I'm looking at my laptop, and I doubt I will ever use the VGA or ethernet ports (which just happen to be right next to each other). I was thinking of trying to add a touch-screen (though that doesn't do anything with my spare ports), maybe Kinect (though I doubt their is room inside for the boards). I looks like the ethernet is a PCI-e connection (shows up as Atheros AR8151 PCI-E Gigabit Ethernet Controller in my Device manager), so maybe replace that with a PCI-e SSD drive?? There is also a Bluetooth chip, which I'm sure I'll never use, so can ditch that if I can use the motherboard connector for anything. It says it's a USB device, but I'm not so sure. What do you think? Any suggestions? The laptop is a Lenovo U260, not that it matters.
