The CPU is a great choice, and the motherboard isn't bad either.
With the RAM, I would go with the OCZ. It's better and cheaper than that Corsair.
Either hard drive is a good choice. I would go for the bigger one as its only a few bucks more.
The video card should be fine for low powered programs that aren't graphically intense.
DVD drives are fine
For the case, if you are decided on one of those, then I would go for the first one. It has a good solid PSU, with enough power for the system.
Floppy drives really aren't necessary, but if you must, the one with the card readers is the only way to go.
You really don't need the thermal paste, chipset cooler or the cables.
I would buy the OS from a "better" place, like newegg.
