Everything about the Cube is great... except for one very important, vital, and absolutely necessary thing - Cooling. This box runs very hot, very quickly. That's because of two issues: poor venting and a cramped interior where the DVD drive sits right on top of the cpu fan. A bigger cpu fan won't work because the space won't allow it. Cranking the fan speed to max only help slightly. Installed extra fan, but didn't help. CPU temp at 40c after about 30 mins and keeps going up. If ever there is a case that needs side and back venting, lots of it, this is it. But the only opening is a small area at the top of the case where the airflow is blocked by the DVD drive. I run a dual-core E2180, I'm sure an older CPU would not generate as much heat, but what's the point? On the plus side, the Cube can double as a heater if you run it long enough.
