I find it hard to believe such a solid chunk of metal would be leaking, there is pipework in the area that I would have thought much more likely, coolant has a nasty habit of creeping along components disguising the true source of the leak, to try identify the leak more easily I'd take the car for a fast run then stop and get straight under the bonnet leaving the engine running, you'll have the maximum pressure in the system to show up the leak. I'd also advise that if you get a low coolant warning while driving STOP IMMEDIATELY! If not sooner, these aluminium engines do not tolerate overheating and you could land yourself a huge repair bill if it does.
If it does turn out to be the charge cooler I'd just try to find one from a breaker.
