fan question

[Zeb C.]

Hi
I need some advice on installing an extra fan. I have an hp m9040n with 
a IPIBL-LA
(Berkeley) motherboard. I don't really know if there is room for a second fan, 
and if there is what type I should get. I haven't opened it up. I have a 
disability and lack the dexterity.
Thank youZeb
