Decided to try building a Peltier cool box for my DSLR.
The box is the case from an old PC power supply, heat sinks and fans also out of an old PC (Northbridge heat sink and fan on the cold side, CPU heatsink and fan on the hot side).
Peltier unit is arriving tomorrow:

Am thinking of using polystyrene foam or corflute for insulation.
Its all kinda heavy even now, so it might not be workable, but apart from the angle bracket its basically all from bits i had lying around the study and workshop so no great loss if its a no go.
(i have several other hot side CPU heatsink fan combos i can also try)
