This is my first build to replace my computer from 2013. I wanted a PC that would work well for design work, light gaming, and allow let's play streaming from consoles (that is, host my Elgato HD60 Pro). Since most prebuilt PCs were short the spare PCIe slot I needed, or they were otherwise way more than I needed, I decided to try building my own PC!
After my friend referred me to PCPartPicker, I used the Great AMD Gaming/Streaming Build as starting point, and started collecting my PC parts over a couple weeks. The automated price finder was helpful and allowed me to find some good sale items and even a rebate for my power supply. Though it didn't show up in the PCPartPicker, I also found Micro Center had some excellent combo deals for parts on my shopping list, so I bought some parts from them and picked 'em up in store!
Building was a brand new challenge for me. I'd added drives and RAM before, but putting together the whole thing? YOW! Watching a LOT of YouTube videos (many on my phone in between different stages while assembling my new PC) was reassuring and helpful. This article at PC World was helpful and included some useful tips that may be super basic (like removing unnecessary standoffs). I'm new; I didn't even know what a "standoff" was a week ago. https://www.pcworld.com/article/257366/pc_building_best_practices_hardware.html
Though I had my computer up and running on the June 1, I've accessorized with an light strip to contrast with the color of the glowy RGB fan. I also created a little decal of one of my favorite AC villagers for the window. Now Marshal can give me moral support while I mess around on my new PC while awaiting Animal Crossing Switch (or at least its release date).
6.5.19 Update: Flipped the fan to the other side after some advice from a helpful user (thanks!). Bonus: now I can see the fan light better! Someone else asked about cable management, and this case seems pretty nice for it -- the channel on the back right side guides the cables nicely, and includes velcro strips to secure them in place.
