it might be difficult because the power supply cannot support the load. Check the wattage of your powersupply. It could also be because the interfaces for the devices (IDE, ATA, SATA, SCSI) don't match the type of interfaces on the low end system motherboard. Or it could be that they are all IDE devices and the device only supports 4 IDE devices (you mentioned 6 different pieces of hardware). Find out what sort of connection or interface types each device has and then check your motherboard documentation to see if it has enough of each type (or any!). You may need to get a new motherboard - or if you are not comfortable with that a new system :(
It could be difficult if there are not enough empty drive bays or if you do not have a large enough power supply. If you have the space and sufficient power than there is no reason for it to be difficult.
You should be able to as long as the motherboard will support that many hard drives.
Yes.
It's quite possibly one of the single most difficult majors. That said, most people who enter into it find their love of the field drives them to get past the difficulty.

binding
spanning
Floppy diskette drives read and write information to a single rotating disk that can be removed from the drive.
RAID
The difficulty lays in that you can only hook up 4 (E)ide devices One master and one slave per cable. so your hard drives would take up both ide connectors on your motherboard and leave you no way to hook up the optical drives.
you can install 4 OS in a single system
