Well from the 7 PC's I own, do not buy a propriotory Computer! You can buy the components and have it put togethere. That is if you have a friend! Propritary is you cannot add some things to it so you are screwed! You can add but only on what they say! AH sometimes not!
If you have one build you can a take out and put in other components to upgrade! If crashes you lose all! I have had that happen when I had only on one PC! That ius why I have more than 2. Do Not ask!
Well You must remember I am PC Challenged!

That means STUPID!!!!

But have learned some things!
