Reasons why
With R7 3800X CPU, you'd get only 300 Mhz extra base clock and 100 Mhz extra boost clock over R7 3700X while R7 3800X costs $70 more than R7 3700X. To me, that little speed gain on base/boost clock isn't worth the $70, especially since you can OC your R7 3700X and easily get same performance as with R7 3800X,

R7 3700X comes with AMD stock cooler that already has thermal paste included. So, no need to buy additional thermal paste.

Since Ryzen CPUs need fast RAM to work effectively, RAM got a small speed upgrade from 3000 Mhz to 3200 Mhz.

Crucial MX500 SSD is one of the best 2.5" SSDs out there (value king) and i too have Crucial MX500 SSD in use but mine is 1TB in size, but since some funds got freeded up, i replaced it with M.2 NVMe SSD (970 Evo) which is considerably faster than 2.5" SSD, without costing too much more,

While Seagate drives are cheapest of the four (other three being WD, Toshiba and HGST (Hitachi)), they also have the worst reliability. So, replaced it with Hitachi (HGST) drive for much better reliability. Further reading: https://www.backblaze.com/blog/hard-drive-reliability-stats-q1-2016/

Corsair CX750m, at best, is mediocre quality PSU. Since you have expensive hardware in there, i wouldn't put anything below good quality PSU in there. Due to that, replaced PSU with Seasonic Focus+ 650W unit. With Seasonic PSU, you'd get better build quality, better efficiency (80+ Gold vs 80+ Bronze), better cable modularity (fully-modular vs semi-modular) and twice as long warranty (10 years vs 5 years) as well. Also, 650W PSU is more than enough for your PC (where you have 120W GPU + about 250W for the rest of the build, making total 370W).

And finally, added additional Noctua 140mm fan since H500i case can have 2x 140mm fans as front intake. 120mm top exhaust and 120mm rear exhaust fans already come with H500i case.
