My first computer was an HP Pavilion P6720F with a Phenom II X4 840T, 6GB of RAM, and integrated HD4200 AMD graphics. I gamed on that for over 6 years. I recently bought a 1050Ti as a birthday present to myself. Back in 2014, my uncle had gifted me the Cooler Master HAF X which had been sitting in my house until 2017. I decided it was time to do my build.
I bought 16GBs of Corsair XMS3 clocked at 1333mhz for $44 off a facebook group and installed that and the 1050Ti into the Pavilion to hold me over until the rest of my build was done. I spent a good 8 weeks with my dad picking out what CPU I wanted to do with a budget of $250 for CPU and motherboard. I went with the i5 4690K for $200 and the ASRock Z97 Anniversary for another $100, using an amazon giftcard I got to cover the extra $50. The CPU took an extra day to arrive. The Seagate Barracuda was salvaged from the HP as was the Lite-On DVD/CD Writer.
Once all the parts were in my living room, I picked up the HAF X from my storage unit, ripped open the HP and tore out the RAM and GPU, carefully opened the HAF X's side panels and began the transplant. After 6 hours of cleaning the case, putting the components in, going through cable management (which I still suck at), and covering cuts with bandages, the build was almost done. When the CPU arrived the next day, luckily a Saturday, I spent another 10 minutes being as careful as possible as to not break it during installation. When it was done, I installed windows and fired it up.
After installing Steam and some games, it was time to see how it ran. After about 10 minutes, I noticed the CPU was extremely hot, like 99C hot. I quickly shut down Vulkan and tore the side panel off only to find out 3 of the motherboard standoffs had popped out and the CPU heatsink wasn't mounted in it's socket. I pushed everything back in, screwed the standoffs back down, and rebooted. It booted up fine, games ran, the computer was working. No heating issues, no nothing. My first build was a success.
