|I believe you will run into several problems. Firstly, the motherboard and powersupply will not have connectors for a floppy drive and in the one motherboard diagram I found there isn't even an IDE connector. Then the bios probably contains no code for running a floppy drive anyway since the motherboard has no header for it.|
Then the hard drive is mounted vertically which would impede mounting of a floppy drive in what appears to be the suitable point adjacent to the front usb/audio connectors in the bay behind the sliding face door.
You would need to get suitable PCI or PCIE adapters since it appears your machine has one PCI slot, 3 PCIeX1 slots, a PCIeX8 and a PCIeX16 slot.
You have 5 SATA connectors available. If you want a second (redundant) optical drive then get one that is already SATA rather than messing about with SATA/IDE adapters that may not work for you anyway.
