If you really need 32Gb that really limits you to the portable workstations. So macs are out, as is anything thin and light. Add in good native linux support and you’re limited again.
I have these requirements (and 32Gb barely cuts it for me, so it has to be), we use Dell 4700 (old version) and 4800 Precisions (new version). There’s the bigger screen 6800 too.
Key points from a linux POV: Get the intel wifi card not the dell option, works better. Get an nvidia GPU not budget AMD one. And we disable optimus and just run on the discrete GPU. Find they manage their power well enough* that the lost runtime isn’t a huge deal. 2 external screens + 1 internal works ok, only certain configurations of 3 external screens work.
Room for 1 2.5″ drive and a mSata SSD too, so you can have a pair of 1Tb SSDs if you want. The 6800 takes 2x 2.5″ + mSata, and all can have a 2.5 bay instead of the optical drive. So you can have up to 4 SSDs in the big one 😀
Big heavy machines mind, if you can live with 16Gb you can get some nicer thin/light kit including macs.
Whoever said macs are just PCs – show me a PC laptop with NVMe/PCIe SSD in it?** And yes, you might not notice it but we’re talking high end machines in here…
*annoyingly they half the max GPU clock on battery, and there’s NOTHING you can do about it even if you want it faster and know it’ll hose the battery.
**OK ok, certain models of the latest X1 carbon, how’s that battery doing then? 😉
