Even though this one was a hoax I'm going to go with the belief that the G5 iMac will not resemble the Apple Cinema Display look. As previous poster mikechase777 also said to the effect of: "This detracts from every advantage of the current iMac's TFT useabilty". Very True.

I hope they implement screen rotation to a portrait view as that would be a blessing but I don't expect this will happen. As a matter in fact I don't really know what to expect in terms of form factor at all :)

That would assume that one of these are true...

1.) The new iMac doesn't have a G5 ... or...

Apple's already said that the iMac will be G5'ed.

I can't recall if they've ever admitted to working on a G5 Laptop, but that's a pretty obvious research path, and the two are very complimentary, as both efforts are a "how to package" stuff.


I'm just not sure how they could get the space that's, to date, been necessary for a G5 in that thing...

IIRC, the G5 chip is physically a smaller die than the G4 - - the "big problem" has been its cooling. When you look inside a G5 PowerMac case with a Single Processor G5, what draws your eye is its heat sink, which is roughly 3" x 3" x 3" (27 cubic inches).

Heat sinks are like car radiators: they can be shaped into many forms, and although there's going to be some variation in efficiency, a rough SWAG is to say that anything larger than 27in^3 in volume will probably work.

This means that the G5 heatsink should be able to be repackaged into a 1" x 6" x 6" (36in^3) space, as would also a 1" x 8" x 4" (which I consider more likely).

Getting back to an "all in one" LCD box, we add a "laptop's" worth of volume to its back. Let's assume that that's a 12" Powerbook that we've stood up on edge (portrait orientation) behind the right side of a 17" or larger LCD. This leaves ample room - - call it 5" wide by 9" tall - - for packaging the G5 heatsink behind the LCD's left side.

What this all means is that there's enough room from a packaging standpoint if we simply add 1" of additional thickness to an LCD display to package an entire iMac - - including a G5 iMac - - in there. And if you run it as a vertical convection stack, you may be able to really minimize your fans too.

Now my ViewSonic LCD is roughly 1.25" thick, and we're talking about adding 1" of additional thickness . . . that would be 2.25" thick. This is why I say that G5 iMac that's 3" (or less) thick is IMO very possible.

...ok, what you are saying makes sense...but ONLY if those compression artifacts are consistent throughout the entire surface of the image (especially where the colors are supposed to be equal, e.g. the black box). I compress images for the web ALL THE TIME, and what you see in this image NEVER happens the way it is happening here. This picture was manipulated, and that is a fact. sorry, but you (and anyone else who thinks what you do) are quite wrong.

You're entirely wrong. JPEG artefacts happen because of the transformation between domains and quantization in the frequency-domain. Hard edges in the image (such as from black to white) will cause artefacts next to them (uncompensated frequencies) while the rest of the black and white surfaces will be pretty smooth. In other words: the colors aren't supposed to be equal at all. If you want an example, simply look at the pictures posted, the Apple logo is real because the box is real.

I was thinking -- and maybe this is crazy -- can't Apple take advantage of the fact that the iMac makes contact with certain surfaces? For instance, if the new iMac indeed can be hung on the wall like a painting, what if Apple broke the heatsink out of the case, so that when hung the heatsink would physically touch the wall? Any kind of wall would be a better conductor of heat than air is, and the G5 can control itself in order to not get so hot as to start a fire.

Or if the iMac has a stand like that old Apple monitor some were passing off as the new iMac, couldn't the heat sink be worked into the geometry of the base? That base has a lot of surface area...Maybe even the arm on the current iMac could be used to conduct heat away from the chassis. I find that the arms naturally stay a few degrees cooler than the room anyway.

Apple has confirmed an iMac G5, right? But did they confirm a new form-factor? Or are we merely inferring that from the hype?

The only surface you can really rely on is the "desk"...you can't guarentee it will be a wallhanger, unless you're going to provide the wall (eg, an "L" shaped widget that lets it freestand on as desk).

"Possible" does not necessarily equate to "practical". Plus from an industrial design standpoint, PC's and Mac's have essentially "always" been concealing their cooling fins underneath box enclosures.

A really good question (seriously!).

I think we're assuming that there's going to be a form factor change. If anyone has anything specific to point to, please post the "who said what when".

What's important besides speed and performance etc is how it works. The discontinued iMac G4 worked flawlessly in real world terms, the way that the screen glides into position and stays. It was genius in terms of aesthetics and ergonomics. Can Apple match that? Well they have to don't they? If they don't then surely it will be a step backwards? If you mount it on the wall then thats not really as positionable is it? If however it has its own special stand that allows it to be moved and angled like the old iMac then now we're talking! Wouldn't it be cool to have a fully positionable computer on an arm as it were? attach it to the desk or the wall or sit it on the desk. They could sell different attachments for different situations. ;)

Um, actually that would never work. No type of wall would be better than air - walls are INSULATORS by design, so as to keep the heat/cool inside your house and keep you heating/air conditioning bills down. Air is not the best conductor, but works well enough because large volumes of it can be directed over a small surface therefore making it a fairly good method of cooling.

Think about it - next time you are hot are you more likely to fan yourself with a piece of paper or electric fan, or press your face against the wall?

Yeah sounds like everybody's having a ball with those pics. :p

You can almost always tell when people make fakes of new Apple products yet to be released. Because they take pictures from extremely odd angles, with bad lighting, and you can only get "some" of the details in. Usually the main thing is that they show the Apple logo, humors me every time.

I agree. I was telling my boyfriend that it had to be fake. If I was going to spill the beans, I'd at least get some good pictures:p :rolleyes:

Looks like this guy spent a lot of time designing that G5mini. That's a whole lot kooler than those people who just make photoshop images. He actually built his own duplication of a G5, but smaller. I'm sure if Apple were to ever make a mid-size like that they'd dress it up a little more. Maybe a warm glow from the Apple logo on the side of the case or something like that.

...ok, ok...I am convinced I am wrong. My only caveat is that noone ever claimed "I" was a Pshop expert except those who obviously know more about it than I. I simply jumped the gun not doing my homework and assumed that optical flow would be consistent from areas of light to dark.

...a humbling experience and my respect to those who proclaimed the errors of my hypothesis. (All except Stella, who simply insulted my personality and intillect, rather than formulate an solid argument)

..sorry for the distraction to those who were distracted ;-)

Well generally I pick the fan, but only because smearing my sweaty face on a wall would look -- and feel -- absurd.

Put it this way: which is more instantly gratifying after going out for a long run on a hot day? Standing under a ceiling fan or sinking into a cool, leather couch? (The real answer is c] jump in a pool, but hopefully you see my point. :D)

Your comment that walls are insulators is misguided. The walls themselves are not great insulators. The walls keep heat in your home because they generally have fiberglass insulation hidden inside, and how does fiberglass insulation work? Just like winter clothes: it traps air, a great insulator, and keeps it from blowing away. Most dense solids are far better conductors of heat than air is.

Touch any solid object in the room and tell me if you think its warmer or cooler than the ambient air. I'll do an informal experiment right here:

Desk: cooler
Painted wall: much cooler
Framed picture on the wall: cooler
Jewel case: cooler
Metal coaster (not used today): much much cooler

I think my idea has some merit. Especially since a wall-mounted computer won't have much room for airflow.

Hmm, I'm no physics major but I think the reason why this won't fly is because although the solid wall is a better conductor, at the point of contact the conducting material can't circulate like air does, so it will get really really hot.

Thats why fluids are used to cool things, they remove the heat from the local area faster and disperse it widely by effectively adding new medium rather than just conducting it away. I think your suggestion is likely to set fire to the house! :p

Several objections:

1. You could only get sufficient contact with a wall by using a permanent mounting, not by hanging like a painting.

2. Unless you could only use it on a wall, or only on a desktop, neither would be an appropriate way to remove heat from the heat sink.

3. It would be foolish for Apple to put a heat source in direct contact with a wall or a desk - it would be a lawsuit waiting to happen (I can see the headlines now - "iMac Starts Fire").

You may be right about the arm, though - it may be possible to have liquid cooling with a pump in the base, and a radiator in the base or on the back of the display. I can't see that the arm could be used in any other way for cooling, because it is too long and narrow to efficiently conduct heat itself.

Agreed - I knew they were fake from the beginning (After I thought they were real for a few minutes, lol)

Wow - I so want a new iMac now :) :eek:

Kind of funny, though, that this fake isn't too far off from the real thing. No extended non-screen area at the bottom (with the apple logo), but generally it's not totally different from what turned out.
