This $300 gaming PC shouldn’t exist… but it does.
I set out to build the best $300 gaming PC on YouTube — using almost entirely used parts from Facebook Marketplace. Halfway through, the plan changed when my daughter’s PC died, and she wanted something black and orange for Halloween. What started as a challenge build turned into a full-on passion project.
The Build:
*I’m just giving links to generic versions of the parts I used. Please do NOT buy older hardware like this new, its absolutely not worth it.
In almost every instance you can find better and newer hardware at the same price as new-older hardware, if you need help with part selection feel free to leave a comment.
The only New Parts were the CPU cooler which I would not recommend, give at least a 120mm fan for you cpu cooler instead of this 100mm one. Also the Optional Parts were all new as well.*
