After asking around for old(ish) computers from family and people in my area, I soon got an email saying that I could look through my school's computer stash that was about to be recycled. I took 3 school PCs home. 2 of them worked fine, and one had a broken PSU. I decided to really upgrade one of them.
I used Plasti-Dip on the motherboard to make it black, and I'm happy with the way that it turned out. I also spray painted the inside of the case black.
I wanted to upgrade this to the limit. The bottleneck of my upgrading abilities was definitely the PSU and the motherboard.
Upgrades: Before After CPU i3-3220 to i5-3470 GPU integrated to GTX 1050 HDD None to 2TB HDD + 120GB SSD
This PC can run Fortnite at 1080p on Medium/High settings at 80+fps I didn't go with the 1050ti because I was afraid that the PSU wouldn't be able to handle it. I am glad that I didn't because the CPU and GPU max at the same rate. Perfect combo!
Also, I am planning on cutting out the side panel and adding acrylic(Like I did in my Cooler Master N200 build)
