Warranty sucks big time! On almost every part of that computer manufacturer gives 3 years. At least 2 years.
What I can read from their product is: We are not so sure in our selves and our labor.
If you want to find actual good advice on prices and components, ask on xtremesystem's or techpowerup's forums. They are in best knowledge IMHO.
BTW I'm not an expert :)
