No, it is not a problem. However, you will need to add serial ports
either using USB to serial adapters (one for FSK/PTT from MMTTY and
one for rig control if you eventually use a logging program) or add
a multifunction card with serial ports if you can find one for your
computer's PCI or PCI-e bus.
