Workstation for video games development

I'm a 23-year-old stay-at-home caretaker of a parent in the early stages of dementia -- somewhat recently, I woke up to said parent waking up from a nap to tell me to turn the stove off, as it had been turned on while I was asleep, they forgot about it, and went to sleep themselves. On top of that, a recent cancer diagnosis puts the future at further risk. So, I clearly can't be away for eight hours a day at a conventional job if I can't really even be asleep for eight hours at home. I did try, but nobody took me on.

So, instead, I've decided that video game development is my best avenue. Unfortunately, my years-old laptop with a failing keyboard (the enter key has long since stopped working) won't do -- for various reasons. I've assembled a few parts over the years for a desktop workstation, but the bulk of the system's cost is still unaccounted for, and won't be for as long as I can't hold down a job. I need $2,750 to finish it up (motherboard and storage).

I do have a decent amount of prior experience and I have at least one project in full swing, with others existing in planning and design docs. I believe I could get a prototype demo of the former out within the next year.

Examples of my work (Blender 3.6 and Godot 4.2):

Notice: please only donate if you're in a position to do so -- have a stable income and, ideally though not a requirement, have already donated to something more worthy. I'm going to be okay in the immediate term, but long term is where my future is in question, whereas there are people who need help right now.
