My DTVPal DVR has been running full time for over three years and decided it's time be brave, pop her open, and clean her out. Following the very well described and discussed process in this forum, it gets quite clear when you are actually doing it. Had no problems taking it apart (just don't be in a hurry).
What a surprise when opened... very little dust. Some on the vents and on the fan that took a toothbrush to remove. Took it outside and blew it clean. Did find the SATA interface cable was loose and secured it.
It operates on a shelf in a TV stand with no door or back, I have filtered forced air for cooling and heating, in Central Texas. In contrast, my main computer which is on most of the time gets a good blow out once a year... and it needs it. Of course, the computer has much more airflow with three larger fans.
