Built this for my son who is 12 and starting to play pc games mostly on Steam and of course Minecraft. This machine plays games with ease and absolutely no lagging. This was my first but definitely not my last build. I didn't have any problems with the build other than getting the massive cooler on the cpu and it just fit in the case and I put the graphics card label upside down on the case lol. I am planning on doing a few upgrades, ssd, more fans ect. We don't overclock yet... and the machine runs great. Stays cool and quick.
