I have found a new Dell Desktop that I am interested in. I can get it direct from Dell or pickup at my local Best Buy. The system is identical as well as the price. Since I am not going to purchase any extended warranty of any sort I will just have the factory 1 year warranty. That being the case, is there any advantage or disadvantage as to where to buy it from? Wherever I get it from, it seems like after purchase I will be in the same position for the next year. Is there any thing I am overlooking? Thanks.
