This build was ultimately a bit overkill but what my family wanted was a compromise between power for 4K gaming, presenting, and streaming 4K content. This build's purpose was our first step into just having one pc for all our content and getting ready for removing our cable plan. Building it was kind of frustrating at times but nonetheless, worth it and a success. The PC is set as in a living room setting.
Parts run down & explanation: CPU: Intel Core i5 8600K - There is no real big reason why we decided to get this CPU but I thought it was a good middle ground so we didn't break out wallet for an unlocked i7. Plus the CPU was bundled with the motherboard at Microcenter so we got 50 dollars off both the CPU and motherboard.
CPU Cooler: Corsair H80i v2 - I personally trust Corsair's products and that goes for the cooler, we wanted something quiet and would keep the CPU cool in a small area. However, the tubing was really stiff and I know the radiator is in a weird place making the tubing flex a bit more than I am personally comfortable, however it appears to be fine which I am okay with. But I don't have enough experience to know if the flex and bend currently on the tubing is too harsh or if it's okay so if you like, please state your opinion or experience about the tube bending in some of the pictures above.
Motherboard: Asus ROG Strix Z370-I Gaming Mini iTX - Motherboard has what we need, SPIDF port, decent placement for 24-pin, 8-pin, and USB 3.0, a 3-pin Addressable RGB Header (sadly not 4-pin), 2 M.2 ports for expansion later down the road, etc. Plus it was 50 dollars off.
RAM: Corsair Vengeance RPG Pro 16GB (2x8) - We definitely could've saved money here without the RGB but we got that dual sided tempered glass side panel to show off some lights.
Storage: Samsung 860 Evo 1TB SSD - My father wanted enough space for all the current games, our array of software, and archive.
GPU: EVGA GeForce RTX 2070 XC Gaming - My family isn't heavy on gaming but my father and I wanted something that would allow us to game at 4K comfortably without sacrificing too much quality or money. Also we may get a VR set-up in the next upcoming year so I feel as if this GPU is a good buy.
Case: Phanteks - ENTHOO EVOLV SHIFT Mini ITX Tower - When we were looking for Mini-iTX cases this one really just stood out to everyone despite it being as tall as a regular tower as a plus it could be mounted on its side and that's what we did for the setup.
PSU: Corsair SF 600W 80+ Gold Power Supply: Wanted some headroom for power so we opted for this power supply.
In the future we plan to get a wireless gaming keyboard and mouse (so far what I've decided on is the Razer Turret but I'd like to hear from you), and a NZXT Hue 2 Ambient Lighting Kit.
