Can you give some examples of what was taken from the garage and house? This would help paint a picture of what the robbers were interested in.
That activity could always be a decoy, of course, to throw you off the scent; or it could simply be that the thieves really were interested in those items that they took and not your computers and electronics.
There are good reasons not to take large electronics: they are not that easy to turn into cash, and they are bulky items: poor dollar to volume/weight ratio. It's much better to steal actual cash. Or traditional valuables like gold.
What's better: a computer monitor you can hawk for 50 bucks at most? Or 4 grams of gold from an 18K ring, worth some 100 bucks? Or an actual $100 bill? This is why thieves went through drawers and cabinets: they want small things that are dense with value, and cash.
As far as electronics goes, small stuff like smartphones and tables packs more value.
I wouldn't get all paranoid. One thing to do, though, is to monitor your network traffic, especially outbound, to look for any suspicious activity.
