Any tips on cutting a blowhole on the edge of the recessed rear of a case? Recently got my rotary tool and cut out my 120cm intake hole, but the optimal, and actually all spots, for an exhaust fan fall squarely in the center of that annoying recess.

Drill.
I assume you mean using a hole cutting bit...?Quote:

Sounds like it's time to buy some tools
I've always thought that if I ever mod a case, ( Practice with a scrap one first) that I'd make an exhuast in the roof of the case and give it a cap to prevent anything falling in.
This is as much a question as it is a statement. Everyone knows that heat rises. So why aren't most cases designed with intake on the side blowing onto the mainboard and exhaust at the top?
It's always bugged me??
Are you offering?:rolleyes: :D
That's exactly how my new case is going to be and it should be done within the next week to two... Everyone knows there are pictures to come :)

No mate - lots of small holes, keeps your fingers out too.Quote:

Good point...didn't think about how hard it would be to fit a grill...Quote:

Mate. I doubt anyone should be allowed within a mile of my first effort. You'll be wanting kevlar gloves and goggles to operate your PC. Any good legal eagles know about writing disclaimers. :D :knife:Quote:

You have to look at the layout of the interior of a nice case. The intake/s blow air over the hdd/s at the expansion cards where it rises and is pushed out of the case by either the exhaust fans or the psu. So in essence, the hdd/s, vid card, and cpu are all included in that heat loop. As the DVDROM/CDROM/CDRW really don't generate much heat you have good cooling. Also, a hole on the top of your case is just begging for crap to find its way in.Quote:

I know what you are saying, I agree about the hard disks but :).....
Most cases have the intake at floor level (looking at full towers in particular which arent often used on desks). So these fill with loads of crap clogging and destroying all the fans in the case.
I get what you mean about the hole on the top too but I don't think it would be at all difficult to design a case that lets hot air out and keeps things from falling in.
Check this out
I found this in my CTO magazine while taking the kids to the pool.. I think perhaps a shade too much information.
It uses " The chimney effect " It's a little unusual but the design is really clever.
I think this could be a good unique selling point for some of you system builders. 400W PSU too.
Thats why you install fan filters on the intakes. Clean them once a month and all is well.Quote:

Part of the current design for the heat loop is doubtless due to cost as well. Cases are simply more expensive when they are designed in a non-standard way. If you are going to pay over $150 (which I'm assuming is a low estimate for that 't' case) why not just watercool a standard case?
All in all an interesting design on that case, but it's footprint is noticably different from my current case and I'm not even sure it would fit in my desk.
My current case (budget Super Power) came with a fan in the top panel of the chassis. The slide-on top cover forms a shallow compartment and has a grille offset from the fan. Anything that slips through the grille just drops onto the chassis top panel.Quote:

Don't know about you folks, but the top of my towers are covered in stuff (2*UPS, video capture hub, 2 cameras), it'd be the worst place possible for a fan.
Yeah, the footprint is very unusual. It's actually really inexpensive though. I've seen it for £60 (UK sterling) Which is really cheap given the 400W PSU. Its about £15 more than I'd pay for a basic low range case. Water cooled cases are far more than that. it's called the i-tee case. Run a search and see if it's reasonable where you are??Quote:

I think I might invest in one when my studio starts our next project cycles.
Of the hundreds of cases (Dell, clones and SGi) we have, only one ever came with a filter, and the rest of the case was rubbish :):D. I couldn't ever afford the time to clean them all. Sensible but not really practical for my organisation.
Filters are 3 bucks a pop and if you mount them on the back of a fan it takes all of 5 minutes a computer to remove them, clean them with a toothbrush, and put them back on. I've even seen a modification where you could pull the filter out the bottom of the bezel.
Still, my biggest gripe on that i-tee case: how in sam hell would you put a window in?:D
:D :DQuote:

I've been looking at it too. Pretty effin tough was my answer..
You could have one on either side of the front which might give an unusual effect.
The way I see it you would remove basically both sides of the case and bend sheets of plexi to take the metals place. Easier said than done of course. Complete bragging rights for the first person to do it of course. But the paintjob and bezel mod are where this case really shows some possibilities. Would be extremely easy to give it a Wing Commander\Star Wars look. On second look, if you were a mad bastard with an airbrush you could make it look like a Stalker mech from battletech. Damn that would be sweet.Quote:

You're nuts. :thumbs2: I'd like to see some mods of it.Quote:

Has anyone found a reseller...? Only place I can find is Microdirect in the UK.

This company do exports so it might be able to ship them to the US.
well, i have no skill, so i bought a case that is already modded. IT has a blowhole on top, and i love it.
it has an 80mm exhaust fan on the top
two 80mm exhaust fans on the rear
an 80mm intake fan on the side(center of window)
and a 120mm intake fan on the front.
i also added one of those exhaust fans that mount in the slot area, and one of those 5.25 bay hard drive coolers with the 3 fans. needless to say, it is loud, but my CPU temp has dropped about 15degrees since installing everything in this case. (it now runs at around 111 degress instead of the 126 that it used to)
my point it, a blowhole in the top is a nice thing, so is an intake on the side. i stuck my hand in the case last night, and the amount of airflow was amazing.

When I first saw the thread title, Blowholes, I thought it was another rant about stupid customers...
Anyway, HP was really concerned aboutThey designed their 3000 Series 950/960 with a bank of huge 240 volt fans blowing down from the top and another bank of the same fans blowing down at the bottom of the equipment rack. These fans had so much air flow that they over rode the "heat rises" physics and forced all of the air out of the bottom. Thus, no dust, hairballs, etc. came in through the bottom. And, the intake filters all stayed pretty clean since they were high up off of the floor. I thought it was a pretty good design but as stated above, they were pretty darn noisy.Quote:
