@steter I can believe it! My first 486 was around $2500 (although that included monitor/keyboard/mouse). The cost of systems today is ridiculously low compared to the old days.
She could probably get by just fine with an older system (albeit newer than her current one), but if she’s going to put money into building a machine I’d prefer she get something that will last her a bit longer. I may work out a deal with her to help her buy pieces over time. (At least the pace of obsolescence has slowed down since the 80s/90s!)
Honestly, I’m glad she’s considering the costs! She just turned 18 and is starting to deal with a budget of her own for the first time, and she wants to save for bigger things like a car, so IMO she’s doing a good job of figuring out what she wants to put money toward.
