Should be pretty easy providing that 1) you have room for it in the case and 2) you have an available IDE channel. Basically, if it's not gonna be the boot drive, your best bet is to set the drive to slave and attach it as the slave drive on the primary IDE cable (middle slot on the cable). The only problem I could think of is that because of the age of the BIOS on the system, the BIOS may not recognize the full capacity of the disk. Might be able to get around this by formatting the disc straight from the manufactures boot floppy/disc.
