I didn't put in anything to act as a faraday cage on mine, and I can't get my own cell phone or cordless to have any effects (or be effected) even holding them right beside the case. Can't hurt, but imho not really necessary. The easy way to make one is to line the case with aluminum foil, making su...

I'm not inclined to install software just to look at this. I would suggest taking a screenshot and posting it as an image file if you want comments.

The only advice I have to give in the absence of a drawing is to make sure you isolate all the moving bits to avoid resonance issues.

Most likely you'd gain more from a small fibreglass panel placed behind the computer (see the third pic from the top here ) to absorb the sound coming out the back than you would from the small amount of fibreglass you might find room for inside. You might try to use the vinyl just to increase the m...

Yes, both high density rigid fibreglass and mineral wool are superior for sound absorption to foam. Any worthwhile sound absorption is likely to take up more space than you have available inside a standard computer case, though. Especially if you're serious about not giving up the case window. The i...

Fiberglass IS itchy. To handle it, suit up in a raincoat and don the breath mask and safety glasses. The effectiveness is NOT questionable. It's both the cheapest and most effective way of absorption. I agree pretty much 100% with your excellent post, but I think you're overstating the requirements...

In my opinion, there's no point in complicated pathways, but you can get some gains from some very simple sorts of things based on similar principles. For example, if you were to have an exhaust fan inset from the back of the case by a couple inches, or alternatively shrouded out the back, to focus ...

Well, I'm not affluent at all. But then stealing scraps of fibreglass from work doesn't cost me much, either, and the stuff we use isn't readily available on the retail market I'll admit. Still, you could make something comparable using regular fibreglass bat insulation. It's low density, so you nee...

I read it right the first time, and I simply absolutely disagree. My suspicion is that the noise floor you're working with must be rather high if you've had such success with such noise absorption.

My experience is that the only way to "trap nearly all the sound" is with a full enclosure with no significant openings whatsoever.

I'm going to disagree with Isaac about wood and resonance. Wood does resonate as much as steel or aluminum (probably more, actually), for any given thickness. A wood case with walls as thick as common metal cases would be like sticking a computer into a cello. I'll let you imagine what that would so...

My case has had less dust buildup than most of my previous cases (for the most part cheap beige boxes), and that's with absolutely no dust filter and leaving it untouched for months on end.

I doubt you'd have any significant gains (acoustically speaking) using birch instead of MDF. Certainly not enough to justify that price difference, assuming that price is an issue. MDF is about as easy to work with as anything, too. Just remember that even small screws in MDF require pilot holes - i...

1. Don't use plywood. I repeat: don't use plywood! A normal piece of wood will do well, as will some semi-artifical materials. Plywood, even thick, is just horrible about transferring vibration. It depends on the plywood. Most pro audio speaker cabinets (you know, the kind you see hanging in audito...

There's no particular reason why plywood shouldn't be used, so long as it's thick enough. For sound containment, thicker is better. Cheap plywood is usually spruce, though, and thin spruce plywood is definitely not what you'd want. Lots of pro audio speaker boxes are made from plywood, which demonst...

Remember that wood likes to resonate. You'll likely want to soft mount fans and such. That said, my wood case is almost always below ambient noise levels, and I don't have overly quiet components inside, so I think your proposal is definitely feasible. I'll also second the 'no direct path for sound ...

My wood case has no shielding at all, and I can't get it to significantly interfere with cordless or cell phones. AM radio held within a couple feet picks up a lot of static, but that's true of a great many things. I wouldn't sweat RF shielding unless you can actually identify a problem.
