What's 'off-the-shelve'?

[Joe]

The computer will be built from off-the-shelve parts from La Radio Shacka, a Spanish version of the American Radio Shack store.

Does 'off-the-shelve' mean 'second-handed'?

And one more question:

We see people cheching into baggage claim that purchased 2 seats...

Could you tell me what is 'check into baggage claim'?

Thanks very much.

No. "Off the shelf" means "available for sale, not custom made". Here it means that a store stocks these parts and sells them separately. [Shelve] is a verb; the noun is shelf, but the plural of shelf is shelves.

One does not "check into baggage claim". One checks into a hotel. One can also check baggage (leave them with someone who gives one a claim check). "Baggage claim" is the area where one claims one's baggage after a flight.
