Will these parts work?

Here is my pc (includes all specs)

First I want to know if this psu will work.

here is my motherboard model number thingy in case you need to know it as well.

MSQ-P8H61-MPRODP(B)


I also want to know how to go about putting my pc in the new case, should I completely take everything out of the mobo then reassemble it inside the other case?

That power supply will work. What do you have for a graphics card? If you don't have a power hungry graphics card, you can save some money by getting a lower wattage power supply. 500-600 watts is all you need for a single card system, and that will still give you a comfortable overhead.

I have a gt640 right now, I could also use some suggestions on what I should upgrade too.
