This was actually my first computer in everything except for the OS install. I got it with money that I earned helping my uncle move after watching the Linus Tech Tips "$69 Gaming PC" series, and it served me well enough for over a year and a half. It started its life as an SFF machine, but after the onboard audio fucking exploded, I transplanted all relevant components into an MT chassis and motherboard to accomodate larger GPUs (or any GPUs, as they'd have to be both single slot and low profile to fit in the SFF chassis).
The first GPU I ever got for it was a 2GB RX 560, and I had that GPU for nearly a year before getting a 4GB R9 290 and a new PSU to replace it. After getting my main rig, it became my brother Jonathon's PC, but when he moved out, he did not take it with him, and it returned to me. The R9 290 lived a short life in my youngest brother Gabe's PC before kicking the bucket trying to run VR games. The MT has since sat in my room not doing much except having nebulous plans for a file storage or MineCraft server made from it.
