I ordered it, should get here tomorrow...Im using an attached hub, or can connect direct...All around bummer....I may contact my homeowners Insurance tomorrow, just to see if its worth it, or even doable...Thanks All and Merry Christmas
Good question...never ran one from a hub.
It is worth asking Apple about the repair. As others have said, likley requires a new logic board, which is either $$ or $$$.
Depending on the damage, it may be possible that a third party board repair shop could fix it. Might be worth asking...

The dongle arrived and works fine..Very slight D/L speed difference, if any...
Download...as in internet? Good wifi is typically faster than your internet connection, at least for most folks.
Without know your service, and testing its throughput, hard to know where the bottleneck is. Your iMac has (had) a 10 GB NIC.
Those are pricey. Assuming you could actually use 10 GB speeds...
The low-cost dongles are rated at 1GB as I recall, but for the price, I would not be surprised to see less than the highest rated speeds. Still, should beat average wifi, especially if you ever see any dropped packets or latency.
