cooling options for my oddly-designed Gateway PC?

My main W7 PC is a Gateway DX4822-01. As far as cooling goes it has a massive intake fan over the CPU, a case fan I installed in the back and the power supply fan. The HDD bay sits at the front in an odd tray and there is no cooling or ventilation around it. I run my HDD at 47 C, which might be acceptable but I'd prefer to drop that a bit- seeing as my XP Dell runs its HDD at 42 C maximum.

Alright, so I have 2 internal floppy drive sized bays that are empty, which might house something BUT...

... as you can see the front is a solid chunk of black plastic. Now this front panel does come off, and the bottom area below the DVD drive doors also pops off as a separate piece. I can access the floppy area or even drill some vent holes towards the bottom of the PC if that would help. It's a 5 year old PC, I'm not too worried about any warranty voiding by cutting up the case a bit, or I could just leave the lower panel piece off. Or I could use one of my DVD bays for some sort of cooler too as I only have one drive(well okay, I have two, but that piece of junk that came factory installed just sits there unused after I got an Asus).

I suppose a PCI slot fan may also help to some minor degree but that's at the opposite end of the case, I need some cooling near the HDD bays.

I've attached a pic so others can chime in if they wish.
If this were MY computer, I'd be taking off the front panel and looking closely for openings that allow air into the case, and enlarging them as much as possible without destroying too much of it, for appearance's sake. Then I'd take a close look at any chassis perforations right near the hard drive cage area. If there are a lot of holes there, great. If not, then perhaps it's time to break out the Dremel and cut a slot or hole. Then I'd block off the lower portion where you might normally expect to put a fan so that incoming air would be drawn in directly over the hard drives.

The metal case has plenty of holes and vents in the front, so I can easily drill some intake holes. I keep the one HDD in the lower half of the bay so I can go above that. There is also enough space at the bottom I could theoretically mount a small molex-powered case fan to the front, but it'd be below the HDD bay.

I am also likely to replace my current case fan as it's 5 years old too. I'm using an 80mm fan bt it has an extra set of holes outside those, I think it takes a 92mm fan as well.

I'm also annoyed at the sheer number of fans that have LEDs in them.

Okay, good. I'm concerned a little about where you'll get intake air from in regards to your front decorative cover panel. Is there a slot or some perforations on the bottom? eMachines had those hidden as a slot for your hand, for instance.

For a rear fan, if you want good airflow but don't want to go deaf, I strongly suggest a Noctua NF-A9 FLX. Yeah, they're pricey but your ears will thank you. Some say they're ugly because they're brown and tan but if it's hidden inside, who cares? And with a six year warranty, that fan will outlive the computer.

Noctua make several new fans with a different color. Here are just a few.

I have tried to cool old computer cases and I descovered it is easier and cheaper just to get another case. You can buy a all lot case for $100.00.

I ended up going with an Antec Tricool 92mm from Amazon. It was dirt cheap, has good reviews and I'm stuck using a Molex plug to power it. I couldn't see any plugs on the mobo for a fan- if there are any they're hidden somewhere I couldn't find from just a look in the case. I was also limited to either 80mm or 92mm based on screw hole placement and I wanted to get it here quick so I got it via Amazon before my free month of Prime expired.

I don't know what's in the case now, I got it when I got the PC, it's run well for 5 years but it might be slowing. It has blue LEDs which are annoying when I'm letting the PC run overnight. The computer just leaks blue light from every vent hole. I actually got a Cooler Master fan 2 years ago, and the thing shattered like cheap glass when I tried to put the screws into it because the plastic it was made from was such junk.

As for the front panel, I can pop off the lower half to reveal some unsightly holes. I can't just totally leave the front piece off because the top is a mess of card slots and such, but that flat piece I can remove. Or I can drill holes in. I may very well be able to mount a smaller intake fan down there- it won't be too pretty inside but it'll work. I have to measure space under the HDD tray. Most likely I can do what I did with my Dell and just bolt the fan to the case in a suitable spot.

Yes, my XP Dell... a slim case design with no real useful mounting spots for an extra fan, plus it's designed to lay flat. I had to get a PCI slot cooler and rig it so I could bolt it into the back of the case. That dropped average HDD temp from around 50c to 42c though. Maybe I should also get a PCI slot cooler for this PC. But I also need to be wary of overloading the UPS, but running just one HDD and one DVD drive I doubt 2 or 3 fans will do that.

EDIT- I can comfortably fit a 60mm fan under the HDD tray. I can easily fit a 40mm fan using the existing vent hole sin the metal case, or 60mm if I drill some holes. Although neither accounts for those holes lining up with the fan's own screw slots.

An alternate method would be to rig up a PCI slot cooler to fit down there, which would be easy- but I need an intake fan, and PCI coolers are generality exhaust fans by default.

I went with this as a replacement for the rear fan

This to rig into the bottom front

I'll be running them on the molex connectors so they'll go at full speed all the time, which doesn't concern me because between the AC and fan I run in this room constantly I doubt I'd hear either fan.

Just a general question- why are PC fans still made so poorly and why do I feel like I'm going to break these things trying to get the screws in? Granted, I have broken one- a Cooler Master brand shattered when trying to get the screws in. It seems either they could stand to use a better grade of plastic, or better methods for putting the holes in. It also seems most ever fan I've handled feels flimsy regardless of the brand. Maybe the really expensive fans are better quality but these feel no better than fans from 10 years ago.

Fans come in all kinds of quality grades and prices.

There are hundreds if not thousands of fans you can buy. You just have to pick the ones you want and look at reviews. Or you can pick ones that members have used and recommended.

If I could buy a $5.00 fan to work as good as a $25.00 fan that is exactly what I would do.

There's just no substitute for quality and computer fans like the PSU should be the quiet understated one's always doing there job and never getting the recognition they deserve.
