What are your thoughts on passive cooling? My graph card has passive cooling, so no fans to worry there. Processor is an old P4 (775 socket i think), so i'm not sure about heat issues and possibilities on passive cooling...

Any experience/advice on that?

In regards to passive cooling; some passive cooling still needs some airflow to function. For example, the passive CPU coolers meant for 1U rack servers are built to take advantage of the case fans that will be pulling the air through the cooling fins.

But there are passive CPU coolers that would probably be fine in a cab, as long as there is a small amount of airflow. You could consider on the low end a Thermaltake GeminII or on the high end a Thermalright Ultra 120.

Passively cooled components often rely on the case design to channel air over the heat sinks properly
Not sure how you would make the PCI/PCIE/AGP cards stay in their slots either without the case

At least the MB I am using on my present project has a retention clip for the AGP that is part of the MB.  If you keep the loading off the cable into the card, even the friction from the card to MB connector will keep the board pretty secure.

True convenction cooling with modern CPUs & video cards is pretty much impossible.

Explain please.   ???

Convection is the transfer of heat from a solid surface to a moving fluid at a different temperature.  The only way you can say that would be impossible is for the fluid to not move (even through buoyant forces), the temperature gradient to be zero (technically unlikely), or to put everything in a vacuum (ummm, no).

Perhaps you mean passive cooling (fins without fans).  If so, then there are certainly solutions available that do this, however they do rely on the case fans to provide some form of forced convection.  The only other type of cooling that's available in the main stream is liquid cooling, but that's just a different fluid (air, water, etc are fluids).
