Unless your parents are gamers or otherwise need serious graphical
capabilities, why don't you dodge the issue and spec out cool-running
hardware?  This generation's CPU's aren't the mini thermo-nuclear devices
of a few years ago, and you may be able to replace the existing video card
with something integrated. 

Regarding the dust and cat hair problem: the higher you can situate the box
off of the ground, the less of an issue it will be.
