Case issue

I'm into my computer build (first since 2006!) that I mentioned in a
previous thread. Parts are on their way, and the first to arrive was a
case I bought from Newegg:

I guess I'm behind the times, because I never even consided the
possibility: there are no front-accessible bays to accommodate an
optical disc reader/writer, which I require. I was looking for a case
that was very insulated and quiet and this looked like a good choice,
so now I'm very surprised and disappointed. I have to decide whether to
return it (probably on my dime) or keep it. So...

- I guess I'd be willing to spring for an external USB drive *IF*...
[a] they burn reliable (I guess I still remember the days when the
computer/OS could barely keep up with a burn and you'd get frequent
crap-outs during a write operation). and [b] are the drives within the
caddys replaceable? In my experience, optical (CD/DVD) burners have a
short lifespan and must be replaced every few years. But internal
drives are cheap, so it was no big deal - I consider them to be
consumable items. So, if I can replace the drives in the USB caddys for
$10 - $15, that's acceptible. If I have to replace the whole caddy for
$20 - $40, that's not so acceptible.
