Ive worked in mining for a number of years used to maintain a few P and H shovels 1600 E they E stand for elec they ran Heavy A/C cable down into the open cut connected this to the Shovel this powered a A/c motor which in turn powered a D/C generator which ran the shovel which ran 24/7 it had a filtered fan that pressurized the the whole machine when you tried to open the door on the P and H shovel you had to push it open because of the pressure it had been running for several years before I started work there and inside the shovel was absolutely spotless no dirt or
dust so to me a PC case should have some pressure and if Case Labs sell there filters once they finish the design that will do me .
and far a air flow goes holes or no holes where a fan sits make not much difference . I built a PC case the exact same size as a ATX mother board zip tied the PSU to the side and the top lid just cleared the two sli graphics cards at the time the biggest you could buy much the same as the CPU this went all around the world with a drumming in a band he played it non stop between gigs in the back of a motor home traveling through USA it had mesh sides and a few smaller fans. I zip tied the PSU as some times companies like Qantas would knock him back for weight as hand luggage the case lived for a few years I was surprised but to me cutting a hole in a PC case for a tan hole also make the case loose some strength( one thing Case Labs case have is a chassis) The amount of air that the perforations would reduce is not worth worrying about
I can remember a Mechanic that was worried about his son speeding in a car so he removed the Carby and place a plate with a small hole between the carby and the manifold his thinking was it would reduce his sons speed in the car it didn't do any thing the car still did the exact same speed
Realistically the amount of temperature reduction having a hole for your fan and having perforation is insignificant you would be far better off concentrating on how you over clock and reducing your temps that way
we look at thing differently down here each to there own get a hole saw and cut it out if it make you feel better Personally Id hope CL don't cut holes for fans
I called it the yellow peril two weekend work
it kept going for 3 years I was amazed Ha ha piece of junkEdited by HG02 - 9/16/13 at 4:21am
