Can this choice of componets run in a positive airflow setup

[IKIKUINTHENUTZ]

I was wondering if it's a good idea to run a fully passive system (including psu) in a positive airflow pressured case w/ one 92mm intake around the hard drives and one 80mm intake blowing top down to cpu area, with 0 outtake fans in this case?

However my worry is that all the components make considerable amount of heat (of course nothing is overclocked for quite sakes).
E8200 w/HR-01 3U
Intel P965 w/HR-05 on chipset
2gb of ram
HD 4850 w/hr-03 rev.A or Auras fridge
Silverstone Nightjar 450w
2 hard drives.
Will such items all on heatsinks with no fans be safe in this case when there are only 2 intakes? or should I reconsider and get a different psu with a fan and place a 92mm outtake fan on back due to high heat components?

It's not a good idea. Your PSU will be fed hot air from the case and will likely overheat, I think. A fanned PSU will spin up the fan if it needs to, which is better if you're feeding it hot air.

Edit: your other idea sounds fine. The noise level won't be a problem.

you should take advantage of having that exhaust fan, especially in a HTPC setup, as heat builds up around the computer from the other components as well.

aside from that, you shouldn't have any problems with that setup. the only thing i might change for something like that is trying to duct the power supply, but in that case, i don't think you can.

the heat will most likely come from the graphics card more than anything else, so running the heatsink with a fan would be the best way around that.

as for everything else, passive is fine, but still, and exhaust fan will be wanted.

thanks all, I'll do the safe approach for this setup.
