I would say this is one of the more nerve racking things to talk about. This is something for anyone that intends on owning a PlayStation 4 or Xbox One, or has one already. Certainly, this could apply also to other CD systems of the last few generations of gaming. The hoopla right now is about cockroaches. For the last few days, some websites have made stories from people that maintain consoles and talk about the issues that they deal with on a daily basis.
One of the common issues is dealing with cockroaches. They explain about how they get in. Basically, the vents on both the PS4 and Xbox One are a good enough size for them to get into the system, shit on the boards, and maybe fry the system to where it won't work. A lot of it they say has to do with the temperature getting hot enough for the roaches to get in, hit the power supply and ruin your system. Also said was not giving it enough space for it to cool.
It is a problem if you live in big cities or apartments. Unfortunately, you might not have a choice in the kind of housing. There are suggestions that they put up. One was putting it higher up and off the ground. That's what I do now these days with my Xbox 360, though my reason is different. One guy suggested mosquito netting for ones in apartments and getting rid of any in the one you live in. Another downside from what I've read is Sony not helping and returning anyone's PS4's if they get sent to them because of cockroaches.
I'm inclined to agree with some of the methods. You have to give your console more than enough room, have it off the ground, and make sure there is enough space for it cool without becoming a nest for insects to invade. It'll probably turn off a few people from buying systems, but I would think they are smart enough to not foolishly leave their systems on the ground. Buy at your own risk.
