The case comes with 1x120mm fan, which i'm thinking will be sufficient. I picked a Micro ATX case because its for my mom and she wants something small. I'm assuming that will have enough room?
It will be used for the web, office applications, itunes, watching videos (not hd), and she will probably want norton installed. Reliability and long-lasting is what i'm aiming for.
I was originally going to get the WD Caviar Black HDD because I somehow thought it would be more reliable. Is the Caviar Blue just as good?
Your list looks great. That's a very solid case with a quality EarthWatts psu. Both the case & mobo are mATX. Yes, it's enough room.
The Intel graphics can play HD smoothly, in case she will watch full screen HD (youtube).
Blue is slower than Black. Both are good. Black is the warmest. I'd stay away from Green which is the slowest of the pack, but may be what green people want. The other difference is voltage which is negligible. The real power saving is in the cpu which by default will throttle down to save electricity & up when it's busy.
Both cpus are different in terms of prices & speeds & voltages. The price discrepancy could just be that e-tailer. In the west, 540 is more expensive than 530.
