This seems like a great price for this system, it seems to be a similar model to a Tesco deal a while back, albeit with no screen, and £70 cheaper! This would be a good PC for use as a media centre, or just general home use.

POSSIBLE FURTHER DISCOUNT
If you need accessories with you pc (mouse etc.) add whatever items to basket for click and collect (including codes of course) and head down to your store.
Get one of the assistants to price up everything you want, and then tactfully see if you can get a manager to reduce the price etc. Purchasing accessories is the best way to induce a reduction as there isnt a great deal of mark up on the PCs themselves.
If you cant get a better deal this way just head over to a cash desk and get you click and collect ;-)
