    I am planning on building a small form factor PC but it will need RS232. I don't know for sure if there will be room for an add on card for the RS232. Is there a usb to RS232? If so, will it work as good as an add on card?

    Usb to RS232 adapters/cables are common (on Ebay) and I assume they work well but I have never used one myself.

    They are indeed quite common and generally work well. Most online computer retailers carry them. There's also some that do COM port retention if that is crucial to you, all port settings are retained in the event that the adapter gets unplugged or plugged into another port. Generally I've used Startech branded ones.

    The only thing you need to be careful about is power requirements. Serial ports will supply more power than USB.
    Also if the device is analogue rather than digital the mapping may be difficult.
