It kinda bothers me when you say your second system. Really, if you pay $400 for a console, you should only have one. I have a used PS2 that hasn't had problems for the 3 years I've had it. My SNES and N64 are in good condition as well.
Now, I figured it'd be a bad idea to shove the 360 in an entertainment stand. Would it be okay if I set it on top of my stand (this is where my friend has hers set up) or if I made a wooden footstool-type thing and put it, along with the power brick, on that?
Also, I heard about getting an add-on called the Nyko Intercooler EX. It supposedly reduces the internal temperature by a good 20 degrees, but I also heard it can damage the system as well. What's your response on this?
Consoles really shouldn't be this troublesome. :p
