gonna get burned for this but here goes, I have been working with electronic equipment most of my life and was taught early on to always make allowances for ventilation around equipment. I have worked with departments that want all their equipment cabinets closed and locked. I do that only at their request, and leave my cabinets open. Funny thing they have well over 200% more equipment failures than I do with my stuff. Rule of thumb, while its operating leave it as open as you can and keep it dusted out, dust is also an enemy of electronic equipment, blowing stuff out from time to time with a low pressure low volume dry air source works wonders.
