X230 if you'd ask me: 16G RAM, 12M ROM. runs fine with reduced (830K) ME and has a powerful Ivy Bridge CPU. USB3.0, miniDisplayPort as well as docking station has been working just fine for me although handling suspend/resume as well as mounted external storage *can* be somewhat tricky (in some scenarios the X230 would instantly resume from suspend after having been docked once).
Battery life under linux has been somewhere around 8 hours for me, OpenBSD gets about 5-6 out of it but YMMV.
The X series never features more than one disk bay, but this again depends on your use case: I'm totally fine with an 120G SSD, other people prefer a RAID on their W/T model ThinkPads.

You can also retrofit the proper x220 keyboard into the x230 chassis without any major hassle.
The major drawback is the low res screen. I've been considering trying these hacked x230 machines with 2560x1440 screens for 2559Y (about $400?):

As far as I can tell, all of the T450/550 machines have Bootguard profile 4 enforcing verified boot. I wish they had used the measured boot mode instead.

Interesting, I wonder how well these replacement screens would work with coreboot? I assume the proprietary VGA Option ROM won't work with those and native graphics initialisation still needs some work on the X230 either ways.
If people are trying native graphics init I still think it's worth trying the SPARK stuff from nico at least once.
It seems more complete to me than teh stuff I started.

I have one of those. The dock DP lane is "hijacked" to fit the FHD eDP screen. In the BIOS (and in Windows) the signal is duplicated between the non-existent LVDS and DP, consuming more power. However it works very well in Linux with a small patch to the i915 module that disables the LVDS lane and forces DP-3 to be detected as eDP.
I tried doing the same in coreboot, playing with the source code, but couldn't figure out how to. It would be great to have the setup working "natively"

Could you pass me a link to this patch please?
Thanks a lot

There's C code only for LVDS (nb/intel/sandybridge) and eDP (mb/google /link). No support for the PCH's DPs.
There's Ada code now, that supports quite a lot (3rdparty/libgfxinit). It would require a small patch to make the panel power sequencing work along with the DP. I can help you with that if you want to try.

The problem with the X series is that the UI degraded with every gene- ration. Keyboard layout got worse with every generation. X220/X230: only 1366x768 pixels, from X230 on: chiclet keyboard, X240: no track- point buttons!!! The X250 was the first fully usable again, but sup- posedly with BootGuard enabled :-/
If you can't live with the 1366x768 resolution (I couldn't), you can look for a T430s with 1600x900 screen, optionally with a replacement keyboard (the oldest that fits). Everything Klemens said about the X230 should also apply to the T430s. It's just 14" instead of 12".
The X series never features more than one disk bay, but this again depends on your use case: I'm totally fine with an 120G SSD, other people prefer a RAID on their W/T model ThinkPads.
Any 2.5" (7mm height) SATA drive should fit.
