DM600 overheating problems?

The old DM500 had overheating issues.

The new DM600 is basically the old DM500 with the option to use a HD.
Having a HD running will most surely increase the heat inside the box.

Does anyone know if the overheating has been fixed on the DM600 or is it still an issue?

OK, this is what I got from talking to DreamMultimedia.

The DM600 is built the same way as the DM500.
DreamMultimedia states that there should not be any overheating issues of the box as long as you make sure the box has enough air around it.
They say that 5cm on each side, top and behind is enough.

Will be interesting to see if that is true once I get my box.
