I understand your concerns and the current GPU-situation are a disgrace.
CPUs and other components are possible to get by (only some models are hard to find) and hopefully things will improve in the next quarters for GPUs.
But having a machine build for BF4, still running today, is actually not bad. You got value for your money...
Indeed, I picked every piece my myself and had the retailer assemble it and send it to me.
The initial machine cost around 800-900 euros (could had taken a cheaper motherboard and less watts on the power supply in hindsight). Later I doubled the memory, added a second SSD exclusively for BF and WoWarcraft, more memory (from 8GB to 16) and I replaced the Graphics card with a 1050ti after the previous one started to misbehave if I remember.
As long as one does not try to have the graphics at high settings from the purchase to retirment, the machine lasts long enough
