Can you link to these please ? Then we can see the full spec of what you're looking at, and can suggest alternate options where needed from the same place, or maybe a better place than you are looking, but at first look I would get a more powerful PSU, that one would leave little in reserve, if it could manage to start with, I'd also look at a different optical drive, and is there any reason you're looking at vista as opposed to windows 7 ?
