Some clarification needed

Hello everyone, I have spent a good half year with the new PC and need help with some questions:

1) I have half a year warranty, so I opened the PC to see what I can add, and I bring surprise as tied cables, wires of the current tied together with wires Sata hard disk and the CD (picture), in addition to the cables are hard I can hardly move, open any problem if damage cables and whether it is normal that the cables are tough?

2) depending on my motherboard I can not add another CD and single IDE hard disks, right?, I have nothing connected by SDI

3) I should or I will be useful to install a floppy?

I hope that I can help be sure.

Greetings

Hello

if you do not have anything connected IDE,you can connect two devices with this connection either hard drives or DVD or CD, configuring a device as master and slave with other jumpers that there are behind each unit

greetings

Good.

It also believed that the cables are not bend.

The floppy is something discontinuous.

With regard to the only ide, as my colleague said, able to mount 2 more units.
