Here's my story.
I offered to build a computer for a friend two years ago, because he was dissatisfied with his Dell and I had to agree -- it sucked. He balked at the offer, opting instead to buy another Dell.
And it too . . . sucked. And, lo, yea verily, my friend knew it.
He set about finally building his own, surrounding himself in "PC World" and "Maximum PC" issues and subscriptions.
I got a look at his system -- he had purchased the CoolerMaster WaveMaster, and I saw that it was Maximum PC's "Dream Machine of the Year" for 2003, and I saw that it was beautiful.
So, on impulse -- I bought one.
And after several months, I came to the conclusion that it just "wasn't that great" in the cooling category. Not that it totally sucked, but I came to the conclusion that to make it really efficient in cooling by air, you had to do things that would modify the appearance of the lower front case-panel. Actually, it almost totally "sucked", because the intake fans are very ineffective, so any exhaust fans are going to slightly rarify air inside the case.
And, at that time, I obtained a new chapter in the "Maximum PC" holy scriptures. And, yea, verily, the CoolerMaster WaveMaster had fallen from 1st Place among computer case reviews in late 2003, to about 11th place among computer case reviews in early-mid 2004.
Here's what I suggest you do. Step 1. The first thing has three variations. Take apart the lower front case-panel, and cut 3/8" vertical slots where the tiny vent holes are located, and maybe a few extra to the left of the "monolith" in front of those little tiny vent holes. Or (B) cut a 120mm-wide rectangle out of the lower front case-panel, remove the "monolith", and fit a rectangular "modder's mesh" perforated steel extrusion from the hole. Or (c), get a series of drill bits, and starting with the smallest, carefully widen the leetle tiny vent holes. OK. That's three possibilities for step 1.
Step 2. Find a way to fit either a 92mm or 120mm fan between the drive cage and the front-panel. Good luck. It may be easier if you chose the more radical and destructive measure of step 1. If you chose that method -- with the modder's mesh -- you may be able to skip step 3.
Step 3. With scrap sheet metal, automotive aluminum tape, or whatever you think will work, seal off the front fan-frame/shroud so that the fan will only admit air from the case-front exterior, as opposed to recycling internal air.
Your option -- Step 4. Add a side-panel blow-hole over the CPU fan.
Step 5. Measure twice- cut once: Replace the rear case fan (80mm) with a 92mm fan -- and hopefully, you will find a way to fit it back there. But maybe not. I hope you do.
I sold mine to my dentist, who promised me that he was not planning to over-clock the system he was building with a cool-running 2.4C P4, and whose office is always at a nice, cool 72F.
Should I cross my fingers at my next teeth-cleaning and dental hygiene appointment? At least I know about the 2.4C, and the case was a viable home for a hotter-running 2.53B system for a good part of a year . . .
