I am buying few servers these days (HP branded) and I was very surprised to find that in order to reduce the initial offer price, one of the offers had 1 year carry-in warranty instead of standard 3 years on-site support. This dropped the price of the offer by approximately CYP300 (USD 700) on each server. The 3 years on-site support was included in the offer as an option. From this time I will be checking the warranty terms (especially from new suppliers).
