I regret not making my purchase last fall. I live on a fixed income. I've had found myself at the edge of 2 problems:
1.) I need more memory for my OpenFoam Computational fluid dynamics tests on a vehicle body. I've done 12 generations of changes on a vehicle body, but at 64GB, I can only resolve to 10mm, a bit less than 1/2", which uses 50GB of memory--even when using fewer cores.
2.) I cannot afford a laptop workstation/gaming-machine for reverse engineering and coffee shop CAD and a desktop for heavy-lifting. The last notebook, I bought was a Lenovo P15-Gen2, which other than the infuriating heat problem with laptops, has been pretty good. I am still paying it off. LOL!
What I had planned to do: make the computer that you are not supposed to own: a luggable. I had planned to use a MicroATX board, such as a MAG Mortor, and put a full compliment of RAM, in this case 256GB. Then try to fashion some kind of quasi-laptop case, which are like hen's teeth, so I would have to roll--err sheet metal brake my own. Fortunately, Corsair has a new SFX power supply for just such an occasion.
I also thought of buying a used server or workstation such as a Lenovo P-620, or a really old Epyc. I don't need blistering speed, but I need the memory and reliability, the latter of which is a consideration for a computer that needs to crunch for at least a half of a day, all cores, near 100%.
