I spent 10 years on the same budget Dell tower (Dimension E521) I got for my 19th birthday/high school graduation. It came with an AMD 64 X2 3600+ that I eventually updated to 6000+. By the time it turned 10 the only things that were original to that first computer were the case, motherboard, and 80gb hdd. That first computer sold me on AMD, which is the reasoning behind my current build.
I wanted to do an all AMD build, but at the time AMD was just a few months out from releasing the highly touted Zen lineup. I waited and waited for Ryzen to release, and when it did I waited some more. I finally bought my 1800X and MOBO from Microcenter on a 1 day sale combo deal a month after release. I picked up everything else needed from Microcenter, Newegg, and Amazon over the next week. Unfortunately I was also waiting for Vega, so I head to pull my ancient ATI 5770 from my Dell. Over the next 6 months I patiently waited for Vega to release only to see the prices go through the roof at the same time as my personal finances crumble (thanks divorce!). So I continued to wait, until May 2018 when the price on a Red Devil came down $20 below MSRP + FC5, and my 5770 crapped out.
I just put the final pieces together (peripherals, cable management, etc) together this week, so now it's ready to share. I haven't really gamed on it yet, but winter is coming (and I will be forced indoors).
