Looking for Laptop to run Windows Server 2012

I'm looking for a laptop that can run Windows 2012 Server.  The limitation is that it has to be made by a US corporation.  I do know that Lenovo laptops have done so and I have seen the older question about it.  I have an older Lenovo Thinkpad where I've succeeded in installing Server 2012.  Unfortunately, I can not use Lenovo because it is a Chinese company. Yes, they're all made in China, but the distinction is the parent corporate entity is in China not the US.  It's not my limitation, but the customer's requirement.  He can't be persuaded otherwise.  I'm just trying to satisfy the customer.  Please don't tell me what I already know.

Here's the old question, but that doesn't solve my issues:  https://www.experts-exchange.com/questions/28197326/Laptop-that-is-compatible-with-Windows-Server-2012-and-Windows-Server-2008-R2.html

I'm specifically looking for anyone with experience running Windows 2012 Server on a current model laptop, preferably one that supports at 32 GB.  I know such companies don't officially support Windows Server on laptops, such as Dell, but some people have had luck with certain models by using Windows 8 or Windows 7 drivers.  Please let me know which models you've succeeded in doing so and which you definitely haven't or if there were specific driver issues that may not have worked.

I did find one company (Eurocom) based in Canada and the US, that officially sells a Windows Server 2012 laptop with a Xeon processor and 32 GB RAM and includes RAID, but I'm looking for others.  I've seen some old questions on other sites about older model Dells, but I need experience with newer, current models.
