To add a little info about me and my puters.  I don't update very 
often.  I started out with 512Mb of ram and upgraded to 2Gbs.  I started 
with a 30Gb hard drive and upgraded to a 80Gb and added a 750Gb when I 
got DSL and could watch videos.  Basically, as far as power is 
concerned, I added a single hard drive.  I doubt the memory changed 
power very much.  Swapping a 80Gb drive for the 30Gb probably wasn't 
much change either.  The new drive may have even use less power.  The 
only other change was that I added 2 120mm fans on the side to help with 
the cooling.

As you can probably tell, I build it and it stays the same basically.  
Maybe a little minor changes but nothing major.  I figure I will add one 
more drive when I can afford it.  Maybe a 1.5 to 2Tb or so.  They are 
still dropping in price.

Now to reply to some others.
