Reasons why
CPU cooler: Since i5-7500 has locked multiplier (can't OC the CPU) and it comes with Intel's stock CPU cooler, it is more than enough to cool your CPU. AIO water coolers are for unlocked multiplier CPUs (K-series) and viable only if you get at least 240mm rad. AIO with 120mm rad is so weak that it will be outperformed by most CPU air coolers.

RAM: Picked a bit cheaper RAM with gray heatsink fins for better match to the white theme.

SSD: Since Crucial MX300 M.2 SSD is ACHI and not a NVMe drive, Samsung 850 Evo will outperform it considerably.

HDD: For the same amount of money, you can get 3TB HDD. One extra terabyte also makes up the lost 25GB on SSD.

Case: Switched out the black case for a white one to match the white theme.

PSU: Your EVGA 600B series PSU is mediocre quality (Tier three) PSU with fully wired cables,

While my suggested Seasonic G-550 is good quality (Tier two) PSU with semi-modular cables to ease the cable management. PSU also has better efficiency (80+ Gold vs 80+ Bronze) and it comes with 5 years of warranty. If you don't care about leftover power cables inside your PC (which are great dust magnets), you can keep your EVGA 600B and save $70.

ODD: Since the build theme is white and so is the case, had to switch out ODD for a bit better match to your white theme. Didn't get completely white ODD since they don't make those anymore but got the 2nd best with two-tone coloring (black & white).

Wi-fi adapter: Since the GC-WB867D-I is discontinued product, i switched the wi-fi adapter out for newer version.

Case fans: In Bitfenix Nova, you can't see the LEDs of your 2x 120mm intake fans. So, there's not much point to go with LED fans, especially with Corsair AF120 fans that have poor performance. Replaced your case fans with good performing and silent operation Arctic Cooling fans that are also used in my AMD build. Arctic F12 PWM fans are 4-pin and can be run in PWM mode or DC mode, while Corsair AF120 fans are 3-pin and can be run only in DC mode.

Keyboard: I removed it since keyboard is personal choice (among with PC case, mouse, headphones and speakers) and i don't think you'd be happy with the clicky sounds of Redragon K552 switches that feel and sound similar to Cherry MX Blue switches.
Here's a nice video to watch about different Cherry MX switches,

If you want to have mechanical KB, do as i did, go to any PC hardware store and ask to test out different KBs with different switches. This way, you can pre-test different switches and make a better decision before KB purchase.
Before i went to the store to test out different Cherry MX switches, on paper, the tactile Cherry MX Brown switches seemed to be the best. But in reality, while testing it out in the store, i didn't like the tactile bump at all. So, i ended up going with Cherry MX Silent switches that are same as Cherry MX Red switches but much quieter. My KB is Corsair STRAFE RGB that i use on my Skylake build, full specs in my sig.
