1. A compact electronic device comprising:
an outer plastic housing;
an inner casing arranged inside the outer plastic housing, the inner casing having a high-voltage section and a low-voltage section, the high-voltage section configured to support one or more high-voltage electrical components, the low-voltage section configured to support one or more low-voltage electrical components; and
a single fan configured to draw air from outside the outer plastic housing, move the air through the high-voltage section and low-voltage section, and exhaust the air through one or more exhaust vents in the outer plastic housing;
wherein the inner casing is configured to isolate the one or more high-voltage electrical components from metal portions of the low-voltage section by at least a certain separation to meet clearance and creepage safety standards.
