It's an X1 carbon Gen 13, yeah similar to the aura. I think the little x1 nano might be nice too if you need something really small, that one is quite interesting, but the price is very strong. Of course if you get it from work then job done.That's what the X9 Aura (which is what I assume is pictured above) has, above reduced weight.
What I used to do was boot the box off a freebsd live usb, and take the drive out. Even back then there was so much ram (4GB) that you could get the whole thing running in ram with squashfs. Sadly the freebsd live image I used to use (frenzy) seems to have gone out of business, but I think there are other freebsd live images around. You need a live distro with a TORAM boot option, I think the toram idea originally came from knoppix. In a modern machine with 16GB ram you could get an entire system with kde plasma loaded and still have lots of memory left to run it in. Once you've loaded into ram with TORAM you can pull the usb stick out and everything runs nice and fast from memory. Just don't pull the battery out.
Frenzy is here http://frenzy.org.ua but I think they stopped making new versions years ago so it's way out of date now. Looks like their ftp server is down too. There is nanobsd but I haven't tried using that, I'm not sure that is the same type of thing as frenzy. A modern version of frenzy based on 14.3R would be a nice thing to have (are you out there, technix?
