Just built a new computer maxed out everything except for RAM and the GPU.
I had 32GB of lovely 8GB DDR4 1Rx4 ECC'd Server grade DIMMS (stable and responsive). My plan to go crazy with 2nd hand server RAM went balls-up when turns out my over the top motherboard doesn't support 1Rx4, bloody brilliant! So stuck with a spare 4GB stick for now.
The GPU is just a spare one i have laying around (got 6 GPUs, 4 in computers). I will be swapping my old rig that has a Radeon 550 (equivalent to a GTX 1030, same gen as well)
So here is a lovely screenshot of my bodged computer, eith a top of the line CPU, motherboard, with only 4GB of RAM and a 9 year old GPU (and a Free Speech Flag to top it off)
Basically a workstation for professional development and gaming on the side.
End goal config is basically Xen base and 4ish VMs (when I get more RAM), Linux for Dev with whole of JetBrains Toolkit Running (also when I get more RAM), Firefox open with ~700 ish tabs avg open (when i get more RAM), Debian VM for Docker, automated tasks (compiling) and a rootkitted Windows VM on the side casual social gaming (solitare, chess, tetris, Fortnite, Ghenshin).
Maybe ML in the future when I am employed again and decided to invest in a GPU. Also video rendering with Blender (the best FOSS video editor, slightly better than shotcut) and handbrake (+ MakeMKV) for those DVD and Blu-ray rips (legal in the UK while in possession of original medium).
