The listed CPU and mobo combo, a case and some ram are all compatible. You should also be able to reuse your HDD(s), GPU, ODD(s) and OS. Keep in mind you can only use up to two IDE drives, any more and you will need a PCI-IDE controller card.
I also recommend you upgrade your PSU to a more recent model. Older PSUs can be unreliable and can fail at any moment. No-name and low quality models can destroy your PC when they fail so its better to invest in a quality brand like Corsair, Seasonic, or Antec to name a few.
There is a 620W and a 520W Seasonic PSU combo with your case.
