Infra is my PC, it uses an i7 7700k at 4.2 GHz, a 980 Ti MSI Gaming 6G OC, Gigabyte Aorus Gaming K5 Z270X motherboard, 16GB of HyperX Fury DDR4 2333 MHz RAM, A Fractal Design Kelvin T12 AiO, Corsair RM750i PSU with Corsair Custom Black and White cable set, a Samsung 970 EVO 500GB m.2 nvme SSD as my boot drive, a Patriot Blast 240GB SSD for some extra games and a 1TB Toshiba 7200RPM HDD mainly for backups. The whole build is housed in the beautiful Silver Dark Base Pro 900 by BeQuiet!, and also features a DVD drive (don't ask why). And that is basically it, the build has served me for 4 years already, and in that time had many upgrades. I can't list them all, but I did upgrade the motherboard, PSU, cooling, case (2 times), SSD and most recently going from the i5 6600 to the i7 7700k. The OS that I am using is Windows 7 Professional SP1.
