Can you add a grill to the top?  Hot air needs somewhere to go- and it goes
up.    If you have no vent above the PC, the one at the bottom won't help
much.  I'm building a proper wiring closet at the moment, with a vent at
the top of the cupboard into the room adjacent- there is probably enough
leakage at the bottom to make a vent unnecessary.  There are vents
available in B&Q etc for blocked up fireplaces etc that would probably
suffice, and look unobtrusive.

The down side is that I would expect a black 'plume' to develop on the
ceiling above where the vent is, as the hot air will tend to carry dust out
and deposit it on the ceiling (same as you get above radiators and wall
lights eventually.  It should be reasonably easy to clean it though!

Can't help there, but it might be possible to add fans to the PC to get air
moving through it more effectively.  The industrial PCs we use have 2 fans
on the top of the case, blowing filtered air across the cards and drives-
maybe you could modify your case similarly?
