Yes, but the cooling slats/air vents are punched in the metal after plastic is applied, at least in my case, as the removed plastic had slits in it. Good catch though, as it's not apparent that there is plastic on the metal shell.
I thought perhaps the power supply was weak, and the extra draw from the USB drive was taxing the supply, but after some voltage/amperage tests I found the drive only consumed a few watts of power, and voltage levels did not drop enough to cause concern. Some power supplies just run hot. The heat sink on the chip on the main board gets very hot as well.
This was noted after over 4 hours of recording/playback. Neither of my HW-150 units get hot.
Are you using a USB hard drive with your unit? Are you recording/playing back OTA HD? Not sure it makes much difference, but good to know for troubleshooting purposes.
Could be different versions of the box, but the heat issue was noted early on by videobruce in post #4 " This will power a 2 1/2" drive, but note the PS does get hot, but it hasn't failed for the time I have used it." http://www.avsforum.com/t/1465875/iview-3500stb-tuner-dvr-owners-thread#post_23143526
and post #5 "I also have measured temperatures on the main board and the PS since I'm powering the drive off the PS of the 3500 just as I have been doing with the VRX.
The highest temperature on the main board is 150 degrees with a room temperature of 75 degrees, recording.. But, temperatures of the PS are very high with a drive powered. I'm getting inconsistency of the readings depending on the angle and direction I aim the IR thermometer. Unfortunately, I don't have a 2nd IR thermometer I can measure with to compare.The highest reading has been 215 degrees. That is way too high AFAIC. The obvious solution is a fan, but there is no switched 12v available, so it would run 24/7 since the 5 & 14 volt lines of the PS are always hot. The only way would be to use a thermistor so the fan only runs when it needs to. Anyone chime in on this?" http://www.avsforum.com/t/1465875/iview-3500stb-tuner-dvr-owners-thread#post_23143527
I suppose I shouldn't worry too much about it, as there doesn't seem to be that many reports of dead units. And I imagine a different PS could be swapped in, outputs are 5V and 14V, but 12V would prob work.
