I purchased this PC in Summer of 2018 and I'm still in love with it, easily the best PC purchase I've made.  It's quiet, efficient, and great for gaming.  I've since upgraded the GTX 1080 it came with with an RTX 2080 and installation was super easy took less than five minutes after watching an installation video on youtube, but before I did that I asked this seller if he thought the power supply my PC came with was enough to handle it and they said it would and they were right, I've had no issues at all.
