Here is a list of upgrades:
i7-4810mq, additional heatpipe (in pictures),
16gb ram,
synaptics track-pad from t450 - so it's usable if you decide to hackintosh
480gb ssd, and 120gb ssd (one of these uses the disk caddy that replaced the cd drive)
docking station with keys,
90w power supply,
9 cell battery, also include the original 6 cell as well.
I maxed out the upgrades on this machine and would have love to keep it if I didn't need a gpu now.
Notes: There are rubber strips on bezel of the screen, It is there to prevent the trackpad buttons from contacting the screen. I've had them on since day one and I recommend that you do not remove them
The additional heatpipe helps a lot, but using throttlestop at -50mv also stop the fans from having to turn on a lot of the time. As you can tell from the pics, the laptop is in great condition. I hope who ever buys it will take care of it like I did.
