PROS:
Amazing speed, and extremely quiet! I'm quite surprised that no one has yet given a review to this wonderful piece of equipment. I guess you don't need to. That statement about "you get what you pay for" is very true. But if you actually look at it, if I were to buy a top of the line dual AMD Opteron or Pentium Xeon system with the same basic configuration, I'd be spending about the same amount of money. And as a graphic designer, I almost went totally PC when I purchased a Pentium 2.8GHz HT (Hyper Threading - the so-called "multitasking" want a be Mac processor) for my wife. Well much to my dismay, I was using a demo of Adobe Photoshop CS to test the PCs' skills, only to find out that when I went to save a 160MB file, that I only saved about 7 to 8 seconds of time compared to my 5 year old G4 (400MHz single processor) system. Mind you, they both had the same amount of RAM. That's when I remembered testing one of the machines at an Apple store a few months before I almost made that fatal decision to go PC. I saved a 250MB Photoshop file in about 9 seconds!!! Now, the new G5 that's out is the dual 2.5's. So that means the dual 2.0 machines are $500 less (now, $2,500.00). And if you're like me, and can take a couple of weeks to spend some dedicated time to finding a better price, you can actually save about a thousand or more buying it used. I did. I purchased a G5 dual 2.0GHz, 250MB HD, with 1.5GB of RAM and the extended Apple Care Warranty; the full three years was already included with the machine, for a total of $2,400.00. (...) I was a little scared, because I heard about some horror stories about people who got taken of there hard earn money not to get what they paid for. I even found out that the person who owned this G5 was only 115 miles away. So I picked it up myself. He even had it open so I could try it out first. (...)Then you will find out what the going rate is (and also know who the "scammers" are who are trying to take you for your money). Email as many people that seem to be reasonably priced and ask for three things that you have a right to know; 1) What there serial number is on the machine 2) Where they bought it along with the original receipt 3) Get the owners full name and then call Apple (800-275-2273), to get through to the Apple Care Dept. (from last I checked, ext. 3), verify if the G5 belongs to them and if it's still under warranty. Also, ask if there is an option to extend it to the full 3 years; you will have to pay an additional $249.00, but it's completely worth every penny. I know that I'm going off the "review" topic here, but I believe that it is just as important, because of the fact that these machines are not cheap, and they were not available to buy (because of backorder situations, even through Apple), and I know that people want to save as much as they can when purchasing this system (or one like it). But again, we're going back to the beginning of what I said; "you get what you pay for." Another thing to add about this G5, they designed this machine from the inside-out, not the other way around; like I see in some PC towers that are built. The way this system is cooled is simply incredible. I was just reading MaxiumPC's (Sept. '04) review on case towers that just came out, and still NOTHING can touch the way they built this tower. Please do yourself a favor, if you can, either go to an Apple Store, CompUSA, Best Buy to physically try out a 1.8, 2.0, 2.5GHz G5 yourself, or check out there website (www.apple.com). You'll get more information than I can give here in this review. Again, I want to let everyone know (who reads this), that if I sound bias at all, I'm not, I REALLY was about to switch over to a PC; even my close friends were shocked when I said it to them. I actually felt humbled at one point saying that statement. But I'm glad I didn't make that mistake. If you're looking for a workhorse, this is the machine for you; and I'm ONLY talking to GRAPHIC DESIGNERS, VIDEO PRODUCERS AND THE LIKE; NOT to those who play video games on these machines. If you're looking for a gaming machine, then buy a PC. You'll have more to choose from, with thousands of games and more options to making your PC work better with faster framerates by overclocking the processor and graphics card, (only if you're into that kind of stuff and that you know what you're doing - only if - you overclock your PC).
(...) If you do your homework on this, (Graphic Designers - G5 Mac and PC Gamers - OverdrivePC) in the end, it will be worth it! I hope I've been helpful and good fortune to all who read this.

CONS:
None that I know of. Except I would give it a 9 (out of 10) for ease of use, because I was very acclimated to using OS9. OSX takes a day or two of adjusting, but it is a far better operating system to use in the end.

The G5 is meant to be "the professional's machine" for graphics and video. After you get past the "platform war reviews" on this list and look at the unit and what it can do, it does all it claims and more. Mac has and I hope always will dominate the digital video, audio and graphics markets. Anyone who cannot get this machine up and running out of the box in a few minutes, should probably invest in a toaster; because its obvious you were not meant to use a computer. The latest OS, Panther is sleek easy to use and pretty much runs the machine for you. Its also the only unix based OS on the market with a GUI. Which means that you can slip into terminal mode and run lines of code, while doing several other, heavy duty tasks in the background; that's background tasks that would bring any PC to its knees. By the way, Panther is the only system on the market that truly takes advantage of multi processors built into these boxes.

No matter what the semi pro's and novice users, who are loyal to PC's post, this machine simply blows any windows based/intel system out of the water. I have used every machine available for 25 + years as a film and video editor, (the toughest job for any machine) and Mac is the king of the hill for power, ease of use and reliable service.. for the pro user PERIOD. Anyone who claims to work in a pro graphics shop that is PC based, really does not work in a pro shop; because there are no truly pro graphics shops that are PC based.

The price is as always a bit higher on a Mac, because you get what you pay for. If you are not a professional computer user, get a PC and you will be happy. If you are a professional that needs the fastest machines available, as well as the most reliable machines on the market, you need a Mac G5.

I've been a PC user since the good old days of the soldering iron, my last mac was an old powerbook running OS 6 or 7, either way - it was a long time ago. The main thing thats been keeping me from getting a Mac was price, and I must say - it's getting a lot better. I bought the dual 2.0Ghz configuration from the apple store along with the new 20" LCD (that still hasn't shipped ~_~) and it rocks. The biggest problem people have mentioned on the various reviews is the 64mb card - if it means that much to you, go to the Apple Store on their site and configure your own system with a 9800 or an x800 or a different 9600 if you'd like. I got a 9800 personally. I don't understand how anyone can claim a PC runs faster than this, perhaps with video games but for standard use (this coming from a person to whome standard refers to compiling java) its much better.

To complain about prices or chosen base graphics card is ridiculous. If you want to compare this product with a custom made computer... CUSTOM ADD SOME STUFF TO IT! The price of PC3200 memory is exactly the same for this as for a P4 system. Find 512MB sticks for 115 bucks each and then pop 8 in. Presto, 4 gigs for 900 bucks (AN ABSOLUTE BARGAIN!)It would cost more than twice that on a Dell (Dell=gag!).

I actually appreciate the barebones nature of this machine, it allowed me to save money by pricewatching my memory instead of paying the out of box price. Try maxing out a Sony PC, or even a Dell out of the box, its way more money than if you just pop in some yourself.

Compare this beauty to a Sony desktop, its every bit as slick and its actually usefully slick instead of just shiny to get you to pay more money. And seriosly, PC gamers are ruining the whole idea of computers as powerful tools, and Microsoft is doing a glorios job at promoting this. Win XP is THE video game platform for all the twenty somethings that should really just grow up. Big video graphics cards aren't even used by Windows except in games, OS X panther uses video hardware every chance it gets and enhances productivity. This machine is for work for Pete's sake, look at the price tag. If you're using this primarily for games, you simply have no respect for your dollar. Plain and simple.

About OS X, I would pay 200-400 dollars extra just for this operating system. It is actually worth money to me, VS Win XP which is a dime a dozen. If the speed were the same or slower i would still want Panther, it is quite simply DESIRABLE. It makes me want to work, and it definitely promotes creativity. My PC is like creating inside a prison cell. Panther is like a summer cabin.

Compare this to any similarly priced PC out of the box and you would see that there is little comparison. Compare this to a custom made PC, and you would have to admit that the case and cooling alone would have a market value of 400 bucks. Buy it barebones and add stuff if you're concerned about the bang for your buck. It's simply right for professionals to be open about these machines, Apple doesn't reverse engineer like Microsoft does... it actually comes up with things, and makes using a computer interesting again.

On Apple's web site it says "Designed for whisper-quiet operation." Well, *maybe* it is *designed* for it. But it doesn't *achieve* it. This thing is loud! I'd like to know if anyone with the 2.5GHz model knows whether that is quieter, because maybe that is what I should buy instead. The 2.0 GHz model is one loud puppy, the fan noise is easily as lound as some servers at my office.
