Will that spec meet your needs?
How would I know as you never said what your needs are, what you use it for etc. For what its worth it'll do everything including playing any games, even the newest ones as long as the game will run with Vista as it has a good graphics card, fast processor and plenty of memory.
Don't like Norton, I use the freebies, if I was going to buy a security suite it would be either NOD32 or Kaspersky, probably Kaspersky.
Its a damn good PC and will do anything so I suppose it will meet your needs, might be OTT though depending on what you want.
Heard of the company but no experience of them so cannot comment.
