Upgrade Your eMac
Leo Bodnar writes "This eMac upgrade proves that with some effort Apple's entry-level consumer models like eMac can be converted into reasonably serious workhorse system at very reasonable cost. Not for everyone, but some find it useful!"
This isn't the only old Mac that be somewhat upgraded.
Companies like MCETech sell DVDRW drives for the G3 iMac and iBook.

This all goes back to the original Macintosh and Jobs thinking it was a piece of artwork that shouldn't be tampered with. Most people want a computer they can improve, much like people that mod and tune their cars.
Obviously, it's not that big of a deal to most people, or they wouldn't be buying laptops in larger and larger quantities. I expect the old "you can't upgrade a Mac" argument to be history in a couple years.
Then again, lot's of people have no idea OS X exists.
Sorry, you're gonna be out of luck. All of the titanium powerbooks have the CPU soldiered(sp?) directly to the motherboard. To upgrade, you'd have to completely disassemble the unit and get a new motherboard.
Not cheap or easy. What you want is a machine which has a processor daughtercard (G4 towers, G3 powerbooks). Those make it easy to upgrade the processors.
I upgraded my Emacs to 21.2 a couple years ago and I've never been happier. Having icons in X (even though no one ever uses them) brings a more modern feel, and colours in the terminal is nice to have too. Unicode and multilingual support is now seamless.

By the way, has anyone else noticed how many typos there are on Slashdot these days...
I'm writing this from an eMac right now - but mine is the latest revision with the 1GHz G4.
All of those upgrades were available to me as build-to-order options in the online store @ apple.com
I've got 160GB HD, 1GB of RAM, Superdrive, 1GHz G4 - seems to me I don't need to hack it to make it a decent workhorse out of the box.
Well the author of this article did not actually *replace* the CPU, he only *overclocked* it from 800 MHz to 1.33 GHz by changing some traces on the motherboard. It should work on any motherboard that supports more than one type of CPU, without removing the actual chip. This also assumes, however, that the existing chip will run at the increased speed without additional cooling, which may be difficult in a laptop.
Johnny see warranty go RIGHT out the window.
Why not just hold onto it a year, extend AppleCare, and then later when you want to upgrade, sell on eBay for about 80%-90% of the current price, and get a new one.
Sheesh, you don't have to mod everything, use some logic kiddos

For anyone interested in accelerating/modifying/etc your Mac, there is a huge repository of information at www.xlr8yourmac.com. In particular, it has searchable database of Mac upgrades rated by the people who installed them, often with useful comments appended by the Mike Breeden, the site's owner. It also has a fairly extensive FAQ (although it's not always easy to find the answer you're looking for) on a dizzying list of mac system & upgrade tweaks, gotchas, and little known issues that might be relevant to someone mod'ing a Mac. Finally, the site has a daily news page on all manner of Mac related topics, but most typically involving updates, tweaks, compatibility info, etc...
The compatibility database is great because it's really the only relatively complete resource for figuring out whether something like an aftermarket CD-RW drive is likely to be compatible with iTunes, etc... (A lot of drives are clones of one another, or really similar, and Apple doesn't list all of those on its site, so having a reference of actual compatibility reports is especially useful.)
Unfortunately the forum isn't currently accepting new members, and it seems like it has been that way for a really long time. : (
NOTE: I'm not affiliated with xlr8yourmac.com in any way, except that I visit the site and find it useful.
Think of it like an SUV. Everyone wants and SUV they can go offroading in. They all want the AWD or 4WD models, but how many ppl see anything more than going over a curb in a parking lot?

Step 1: Know what the fuck you are doing.
Working on an eMac can kill you. I'm not saying that figuratively, I mean that if you touch the wrong parts just the wrong way, you can receive enough of a shock to stop a healthy young heart, and die. So if you don't know the proper way to work around exposed CRT's, make a point of learning before you even consider working on an eMac beyond a simple memory upgrade. Almost everything on the eMac is nestled inside a little Pita Pocket of shielding nestled under the picture tube. So do me a favor, and don't get yourself killed just for the sake of a little extra HD space. Buying a firewire drive is a lot cheaper than funeral services these days.
Information wants to be anthropomorphized.
Doesn't matter. CRTs have some pretty hefty capacitors which store a charge even when unplugged. Hit it with a piece of metal in the right (wrong?) place and it'll ground the charge right through your body.
The parent poster has it right... futzing around inside an open CRT is a good way to end up in a box in the ground.
As the othe two posters mentioned, you are a likely candidate for doing something wrong. The issue is with capacitors. Capacitors are used to increase the voltage available to the CRT. The voltage they build up is many magnitudes higher than what comes through the mains. The catch is even when unplugged they maintain their charge, unless they are either properly discharged, or find themselves the nearest human tinkering with them.
:
Just to give you an idea, from Repair FAQ
"TVs and monitors may have up to 35 KV on the CRT but the current is low - a couple of milliamps. However, the CRT capacitance can hold a painful charge for a long time. In addition, portions of the circuitry of TVs and monitors - as well as all other devices that plug into the wall socket - are line connected. This is actually more dangerous than the high voltage due to the greater current available - and a few hundred volts can make you just as dead as 35 KV!"
