Dell 5520 (http://www.dell.com/learn/us/en/555/campaigns/xps-linux-laptop http://www.dell.com/learn/us/en/555/campaigns/xps-linux-lapt...). I bought one for work earlier this year and liked it so much I bought a second for home. Dual Xeons, 32GB ram, 4k display, great battery life, and a body design which feels decidedly mac-like, yet different. In fact, I actually prefer the tactile feel of the 5520. The only real problems I have is the touchpad (currently tweaking synclient to get it just right) interfering while typing occasionally, and the completely crappy experience with the Thunderbolt docking station (it rarely goes perfectly when docking/undocking, but even if it does, sometimes the displays refuse to wake up while docked). All that said, I really dig it. I've had two macbooks in the past, and can honestly say this machine is a FAR better experience and much more cost effective.
