oh yea, bro i saw ur pic, i mean the file u uploaded. I still not sure whether mine is correct, but when i see yours, i still can see there is 2 hole at the drive bay (1 at 5"25 1 at 3"5). It is closed. I remember i draw it on solidwork, it is closed.

-what is the difference between the 2 step files?
-On those 2 files, there are more parts which don't appear in your dbs file (like fans, etc...)
Is it deliberate?
Anyway, you need to do the same thing: creating surrounding box and substracting solid elements.

* Import your step file
* unite all the volumes
*create the surrounding box
* substract the united volumes FROM the box

you created the surroundig box after you united all solid volumes (from your import), right?
Then create the surrounding box.
Then go to substract Real Volumes, and pick the surroundig box in the first panel ("Volume")
Finally choose the united volume in the second panel ("Substract Volumes")
If you don't succeed, post a picture from your gambit window after the substract operation

By experiencing problems and fixing them, you will learn a lot.

Ok if your fluid domain is ready, you can try to mesh it on the fly (it will fail) but all the warnings and errors you will get in the transcript fwindow will be usefull.
You will be able to localize small edges, sharp angles, etc...
But prior to mesh it, I would do a basic tutorial. Send me your email, I will send your a tutorial
