If you put a case on carpet it tends to suck up fibres and dust. This isn't so bad if the intakes are filtered.
On the desk you will hear the computer more and you lose desktop space.
Hm... With an i5 4440 and a Sapphire HD 7870 it will be loud or quiet? While gaming and non-gaming.
These components aren't super noisy.
The graphics card may make some noticeable sound when playing games.
Which case you have plays a big part in how much of this noise is audible outside the case.
Generally cases with lots of vents are noisy, and these also collect the most dust.
