Topower PSU's? I've never heard of them, but for the price you're paying for the kit I'd go with a known reliable brand, such as Enermax, Antec, Zalman, Aerocool or Vantec (avoid the cheaper models in each of their ranges). Also beward of Maxtor drives, probably just my bad luck but every single Maxtor drive I've had ends up whining after about a week or so.
