About a year ago a friend of mine bought a 750ti hoping to buy the rest of the parts for a pc as he could afford them. Long story short, he wasn't able to buy any more parts. My dad had an old desktop he was replacing and I thought I'd try sticking the 750ti in there, but I wasn't able to get the old hardware to play nice, so I found an i3-2120, MOBO, and 2x2gb RAM in a 75$ combo on Ebay along with a cheap air cooler. I already had a 400w PSU that I bought a couple months ago, but I factored the price in anyways.
The only issues I had with this system were with the mounting system for the CPU cooler, and one of the HDD's. With the cooler I ended up needing to zip tie it on. After running prime95 for 30 minutes the temp never went higher than 72c, so I think it will be fine. As for the HDD, it wasn't wanting to show up in Disk Managment so I had to go through the steps of installing windows10 on it in order to format it and use it.
Other than that is runs pretty well. GTAV ran at a solid 48fps average during the benchmark and only dropped to about 30fps at the end of the benchmark with all the explosions.
