HP Zbook first gen here: I can also replace CPU and GPU. I didn't do it and never will do but it's in the user manual.
I upgraded RAM and swapped the DVD with a 1 TB SSD. The HD is still in there, auto shutdown after 5 secs. I use it for storing large files I don't need on the SSD but could be handy to be online sometimes, like raw videos from my camera.
I'd like to replace the keyboard with one without the number pad. Possible in theory but there is no part that fits on the market. The only 15" laptops without number pad at the time were the Mac and I think the XPS, which was overheating. Maybe the problem with the latter is solved now.
