Where is the IDE connector placed on the Mother board?
It's in the middle, sort of toward the front of the case.
It's the only one with 40 pins.
How mouth dismantling is needed to change HD or inset a CD-rom? Do I have to remove the plastic front to be able to place drives in the lower Drive holders.
You absolutely MUST remove the front plastic cover first.
This is not too difficult - just pry it off with your fingers! ;-)
After that, there isn't much work - just slide them out.
... for now I am a very happy owner of an A4000T.
