I forgot to use stand-offs in my computer build. When I first built this, I was a complete and total (dare I say it) noob at building PC's and completely forgot to put the stand-off's in my PC. Now, a year and a half later, I realized that I didn't put them in (as I haven't opened it more than three times, and never took anything major out). Would there be any harm in leaving it as is, or should I carefully put them on? It was a major fuss putting it together, and if I don't have to, I'd rather not do it again. I've run it for about a year and a half, mostly eight hours a day. The computer seems to work perfectly, using the GFX card, the CPU seems to be fine, and all temps are relatively normal. I know that I don't have any stand off's inside, and would like to know what I should do?...
