The eMac is an all-in-one Macintosh desktop computer released by Apple on April 22, 2002. The eMac was a low-cost alternative to other Apple computers and was aimed at the education market, so it retained a similar design to the previous iMac G3 introduced in 1998. The eMac featured a G4 processor and a 17-inch CRT (cathode-ray tube) screen—the last CRT display sold by Apple.

Apple updated the eMac in 2003, 2004, and 2005 with faster processors and additional memory before the line was discontinued. All models could run Mac OS X, but the early models from 2002 and 2003 also shipped with Mac OS 9.2.2.

The eMac case is made of opaque white plastic. The front of the shell features two speakers and a CD/DVD tray (it kind of looks like a face), and the back is rounded to fit the CRT display. To identify this computer, look for the word “eMac“ on the hatch on the bottom of the case. You can also find the serial number written inside the disc drive door as shown in this article. Use Apple’s serial number lookup to find your model.

If you can boot the computer, you can find the exact specifications by clicking the Apple icon in the top left of the screen and choosing “About This Mac” or “Apple System Profiler.“
