The P180 is a great case, that's what I went with my latest build. I like the case because the hdd cage and PSU housing is in a TOTALLY separate compartment at the bottom of the case. And right in between the 2 is an Antec Tri-Cool 120 cm fan. This fan is strong enough to suck air from the front of the case, drawing hot air away from the hdd's, and over the PSU. The PSU fan (most are also 120's nowdays ) takes care of the rest by exhausting it out the back. So leave the mid case fan pointing to the rear of the case.
The outer case covers are made of aluminum and a thick plastic. This is great for noise dampening. The upper chamber can house more hdds but I personnally put all 3 of mine in the bottom chamber for convenience and noice reduction. Now right in front of this upper cage is another spot to install a 120 cm Tri-cool. I put one in there and cleared it of any wiring so it can blow air over my vid SLI's. This is a crucial spot to keep clear of wires because let's face it, the vid cards can really pump out the hot air when your cleaning house with F E A R or D O O M 3 right bro
Also make sure you have another 120 installed in the roof of the case ( make sure it blow OUT OF THE CASE ). This will get rid of any heat disspelled from the cpu. Another 120 at mid level rear of the case will handle the hot air from your mobo ( make sure this is blowing out too ).
Mod your wires well and you will have NO PROBLEM playing in a climate like yours. Where I live, Ottawa Canada, we had ONE HOT MOFO of a summer this year, with a few nights temps hanging around 30 degrees celcius. And my room does not have A / C either. I was also concerned with heat but after about an hour of playing F E A R I minimized the screen, and quickly went into the nVidia panel to check GPU temps and I had GPU#1 was 69 C, GPU #2 was a bit higher cuz it's right at bottom of the case, @ 72 C.
So ther ya have it bro, hope this info helps ya, good luck.
Matter of fact the wife and I are going to Domincan Rep next week to the North side to do some scuba diving so I guess I will be in your neck of the wood huh ?
Cheers
