A computer just for video and slide building?



I think that my current computer is not really up to video editing not just because of the demand that is put on it but because of all the other applications that I have. Surfing the web I have come across a couple of sugestions:

  1. A Novatech Isys Pro 6300.
  2. A Novatech NForcer 420.
    I have two questions:
  3. Does anyone have a view on these?
  4. I think that I read that if one restricts a PC to just video work it does not require an oporating system. Is that correct?
