My husband smashed the computer host tonight. Can the configuration inside still be used?

Generally speaking, the motherboard may be damaged, and everything else should be usable. Check whether the memory and graphics card are broken. If not, it is probably fine. The CPU should be fine, and the hard disk should be fine too. The main thing is to check. Check to see if the motherboard is broken. Of course the monitor will be broken if you drop it.

I suggest you take it to a computer store and ask the boss to check it for you.
