I just put in a new MSI Mb and Athlon AMD 900. I'm running a Voodoo 5 with half a gig of ram. Is it ok to run the system without a case cover.
I have a plastic cover when the cpu is off and I use compressed air once a week to blow out any dust.

2nd, what is the standard operationing temp of the mb and processor?
Tthank you
As long as you have no small children or pets that might put their noses into your box, it's no biggie using a house fan in place of case fans. I've found out that 120 mm fans suck a LOT of dust into my box. An air compressor would be much more economical than canned air. Whichever, watch out for condensation in the air line and liquid from the canned air.
I actually did a test recently where I ran my case open, then bored a 3.5" hole in the side about mid way between the PCI cards and processor and mounted a 92mm fan blowing out. I have a 80mm sucking in at the bottom front of the case. My temps actually dropped 2 degrees with the case closed compared to open with this setup. I like having the case closed much better, it's quieter and safer.
I leave one side of my case open all the time, but I live in a dorm room with no children or pets and I think I can trust my roommates enough to not stick their fingers in my FOP.... :)

Dont get an AC fan too close to your computer.... it's most likely NOT electromagnetically shielded.
