Though I have never built a PC before, i'm aspiring to build one and replace this dusty old mac.
My dream build ....It features a r5 3600 (a killer cpu with awesome performance at the price) paired with an RX 5700 XT( the only decent GPU in stock) though I would prefer and RTX 2080 TI because it would be a perfect match for the 3600. All on a gigabyte x570 motherboard paired with 4 sticks 32gb of corsair RGB ram. As for the storage, I chose a BLAZING FAST Samsung 970 evo as a fast boot drive also serving as a killer games library. A samsung 1tb ssd as a game library asko, and a 2tb HDD as file storage. All of this in a nzxt h510 rgb case because it features cool looking RGB effects (+15 FPS). The keyboard one that all my friends have and the mouse, a Logitech g502 (wireless is +++) And finally, two awesome 1080p moitors, one for schoolwork, the other for ... gaming!
Well that was my dream build,nothing too interesting but I hope I win and best of luck!

And thanks for your time!
