Build went off without a hitch, save for one minor inconvenience.
UPDATED BUILD: Delidded and repasted the stock tim with Thermal Grizzly Conductonaut Liquid Metal. Well worth the effort. Also swapped out the stock cooler for my old NH-D15. Lid doesn't fit flush with it, but I don't mind how it looks and the performance increase is well worth it.
CPU Overclocked to 4.2 GHz - Max temp recorded in OCCT is 53c
ORIGINAL BUILD: The stock AMD Wrath Stealth cooler that comes with the 2400g doesn't fit on the MSI B450I Gaming Plus AC motherboard without a small modification (pretty insane when you think about the fact that it's a stock cooler.) Depending on which direction you turn the cooler, the top decorative ring on the cooler protrudes and hits either the ram or the I/O heatsink. This can be solved by unscrewing the two top screws under the ring, and simply unclipping it from the Wrath Stealth fan. All in all, a very simple step to be able to mount a stock cooler.
~To be Entered~
CPU: "AMD Ryzen 5 2400G 3.6 GHz Quad-Core"
I know this cpu is a bad value compared to the 2200g, but I just wanted to see how far I could push the integrated Vega 11 graphics (aside from the bandwidth wall.) On stock settings; scored an 831 in Cinebench CPU test, 63fps in Cinebench OpenGL. Not bad at all, AMD truly is king of integrated graphics.
Cooler: "Ryzen 5 2400g Stock Cooler (AMD Wrath Stealth)"
Decent stock cooler. As mentioned above, doesn't fit the B450I Gaming Plus motherboard without removing the top cover loop. Aside from that, no issues.
Motherboard: "MSI B450I Gaming Plus AC Mini-ITX"
Going for an ITX build, the choices were slim. I went with this board because it appeared to have the best vrms as well as AC Wi-Fi support.
Memory: "Corsair Vengeance 32 GB DDR4-3200"
Just your standard Corsair Vengeance LPX low-profile RAM. With A-XMP Profile 2 enabled, RAM easily hits the advertised 3200 Mhz speed, with 16 CAS Latency. I chose white to match the color of the case.
Storage: "Crucial MX500 1 TB M.2-2280 SSD"
1TB provides more than enough room. I chose this drive because it had the best price, TBW, warranty, and best marginal speeds for the price (all things considered.) Went with the m.2 form factor because in a case build like this, dealing with less cables really matters in the long run. Drive does tend to get a bit hot due to the lack of m.2 heatsink on the B450I Gaming Plus, but I haven't noticed thermal throttling yet so we'll see.
Case: "Thermaltake Core V1 Snow Edition"
Absolutely love this case. Really allows for great cable management which is important in an ITX build. Nice airflow as well. This case is the reason I chose to do this build.
Power Supply: "BitFenix Whisper M 650W"
Went with this psu because it was the safest, cheapest modular unit with quality components. I'm aware the 650W is overkill for a build like this and that I could've gotten away with using a 450W but the headroom is nice to have should I ever choose to upgrade anything in the future. Modular is perfect for cable management (only need to use the ATX 24-Pin main power and ATX 8-pin 12V power connectors.) Great for cable management in small spaces.
Case Fan: "Thermaltake Pure 20 LED"
Nothing special to say here. The Thermaltake Core V1 comes with a Black Pure 20 fan. I wanted the blue led, so I swapped that out with the Pure 20 LED. Same size, cfm, static pressure, and noise rating except with blue LEDs.
