Step 1,2,3 Mod Results
I then put the system back together again (does that remind you of a nursery rhime too?). And proceeded to run some the tests as per the methodoloy above. Here are the results:

Alrighty, as you can see, there is a big difference in CPU temp between Step1 and Step 2. Everything between Step 1 and Step 2 seem fine, basically everything is cooler. Due to the more controlled airflow of the blowhole located on the left panel. Now looking at Step 2 and Step 3 things seem a bit odd. The CPU got hotter, the heatsink also got proportionally hotter. Everything got hotter except for the darn V3! Now the Voodoo3 cooled off a bit cuz now it's got that big ass fan blowing right onto it, no longer obstructed by cables. Why? Where here is my thought on it, due to the clutter (particularly the 50pin SCSI ribbon cable) air was being channeled closer to the heatsink, therefore providing better cooling. With all the cable clutter gone, air was just hopping over the heatsink, right over it, not around it. This theory is further reinforced by the fact that the Voltage Regulators (right between the CPU and dual 120mm fans on the mobo) got hotter, meaning less air was circulating there. This leads me to the conclusion that for best CPU cooling you should place the blowhole fan just to the right of the cpu. So that the left edge of the box fan is a couple inches away from the top, or right edge of the heatsink. This way air blows down onto the motherboard right in front of the CPU, and then is pulled AROUND the heatsink by the dual 120mm fans. This would give optimum cooling.
I am not disappointed with my blowhole location, as I am going to be progressing towards watercooling. And was thinking more about cooling my V3 (which worked a bit, bloody thing.....). So the solution for me, or people who have not modded their LiteONcases would be to come up with some ducting methods. Ducting would probably have better results than the best blowhole placement, as I would be FORCING the air to go where I want. Just imagine, over 120cfm of air flowing past your heatsink! This case ROCKS!!! If there is enough interest out there, I'll be glad to perform the ducting and let you all know about it. Why don't I do it for myself? Well, I am heading towards watercooling land... where we're going we don't need.... fans... ;) So it's more for you than for me.
Have a good One,

Also, if you could, please keep up posting stuff in the comments and in the forums, so I won't have to answer the same question more than once, and you won't have to wait as long to get an answer. Thanks. ;)
PS: Like 'em models? ;) hehehe
