After reading some reviews online I'm most definitely sure the malt extract is no good, I was wondering if the yeast would be any good (just curious).
That's old. Its' ingredients are toast for a drinkable beer. Yeast is dead for sure. Hops will have nothing to offer either.
But the extract you can still make use of for yeast starters, just crash and decant the beer off. But still wouldn't be as good as using fresh DME.
The hardware should be fine, just check the plastics for cracks etc.
