So, I wanted to write this review because I think my original problem was on my end and not the Hero Box. I have changed my review from 1 Star to 3 Stars to be fair to the Hero Box.I originally gave this PC a 1 Star review because it seemed to be overheating while playing GZDOOM with the Brutal DOOM Mod and large maps that were procedurally generated by Oblige.However, sense that time, I have installed Parabola GNU + Linux Libre on it. This is a completely Free Software OS based on arch linux.I compiled GZDOOM from Source Code and have been running it fine with the Brutal DOOM Mod and extreme map sizes from Oblige.I think compiling it from source on a rolling release (which has newer libraries) has allowed GZDOOM to be more stable than the pre-compiled .deb packages the GZDOOM site offers for systems using a .deb package system.My theory now is that the pre-compiled build may have had some sort of 'memory leak' or something. Who knows. But, the Hero Box does seem to be able to handle long sessions of GZDOOM without overheating now.I felt it only fair that I update this review because the fault was not the Hero Box.That said, I only updated this review from 1 Star to 3 Stars because I am ultimately still not super happy with the Hero Box. Because, if someone were to ask me if I would buy it again or recommend that someone else buy one, I would still say no.While GZDOOM doesn't seem to be overheating it anymore, I am still very sad that I purchased a Mini PC without a fan. Other companies sell models with fans that I might end up buying someday. A PC, even a small one, really should have a fan. That, and the Celeron Processor really isn't as capable as an i3.I know it's my fault that a purchased the Hero Box with the specs it had. But, I certainly take this purchase as a teachable moment. The lessons learned: If I buy a Mini PC again, make sure it has a fan and at least an i3 CPU.
