My friend told me that his co-worker was looking for a PC to game on, and I jokingly told him he can buy mine (i5-6400 / GTX 1050ti) if he wanted, since I was planning on a new build later this year anyway. A few minutes later he said, "give me two weeks" and I had to buy all my parts within that window. Sales tax is included in prices.
Most of the parts I ordered on Newegg and Amazon. Overall, I had no problems with the parts. I originally ordered a STRIX B350-F motherboard, but the lack of a PS/2 port was a deal-breaker for me and I found the B450-F for $10 more at the time. A bit ridiculous to say, but looks played a factor as well...
UPDATE (5/19/19): As of 5/17/19, my RAM crapped out on me. I had numerous BSODs and browser crashes within a few hours, with the dump files showing memory-related issues. I am currently using a temporary Patriot 2400 MHz 16GB while I am currently in the market for new RAM...
UPDATE (6/5/19): I have replaced my Team Vulcan 16GB with a set of G.Skill Trident Z Royal 16GB 3000 MHz. My current plans are to RMA the Vulcan RAM and sell it once I have received a replacement.
The first thing I bought was the Ryzen 7 1700 for $135 on Rakuten. I was a bit torn because the Ryzen 5 2600 was on sale for just a little more, but I figured the extra cores wouldn't be bad for what I planned on using with this build (moderate gaming, recording/rendering, Excel, university work, Stata/SPSS, etc.).
My first build had an NZXT S340, and I knew that I wanted to stay with a similar case. Since my original build had no RGB and no actual color theme, I wanted to go for a white/gold/silver theme this time. I decided to keep the protective plastic on the tempered glass for now, as I'll be moving next month.
