Great, thanks, that's the answer I was hoping for -- clear and
complete, I mean.
I'm not that thrilled with my new case. It's a no-name case that
came with a 420 Watt power supply, and only cost $35, but to some
extent, you get what you pay for. The sheet metal is very thin. My
five-year old Dell case is just about twice as heavy, which says a
lot about the difference in thickness of the metal used in the two
cases.
I had another case, even more solid than the Dell, from an old P2
computer, but it didn't occur to me that I might be able to use it
with a modern motherboard. But I'm guessing now that it is an ATX
case, and that I could have bought a new power supply and put all
my modern parts into it, and gotten a more solid (and quieter) box
as a result. I would have had to give up multimedia plugs on the
front panel, but I probably would have done this had I known the
new parts would fit.
Mind you, the case I'm using isn't a terrible case (I like the
buttons and the lights), it's just not as solid as the Dell or the
other box. I am going to stick with the flimsy case for a while,
and if it still bugs me after a few months, I will think about
transferring the guts of the computer to the older, more solid box.
