Imac 20" N. American model to be used in Europe

Question

I am having an iMac 20" come from Canada but I would like to know if they absolutely work here in Europe. Apparently there were manufacturing processes/decisions with the iMac G5 that lead those models to fail if plugged in to European sockets.
Of course, we all know that physically the outlets in North America and Europe are different but will the internal power supply handle the different electrical standards?
Can anyone verify, without a doubt, that the North American Intel iMac 20" will absolutely work in Europe, granted I will merely need an adaptor to fit plug into a European outlet.

* August 31, 2004 — Apple releases an all-new iMac line, with both the LCD screen (17 or 20” widescreen) and computer (including power supply) contained in a 2” thin flat-panel housing, powered by a PowerPC G5 processor at 1.6 or 1.8 GHz, Serial ATA hard drive (ATA in the Education Model) and an Nvidia GeForce 5200 Ultra GPU. USB 2.0, FireWire 400, 10/100BASE-T Ethernet ports, a V.92 modem, a video-out port, an analogue audio-in jack, and a combination analogue/mini-TOSLINK audio-out jack (like the one in the AirPort Express units), as well as the power button, are all arranged at the rear of the unit. The enclosure is suspended above the desk by an aluminum arm that can be replaced by a VESA mounting plate, allowing the unit to be mounted using any VESA-standard mount. Apple boasts that it is the slimmest desktop computer on the market. The iMac G5 is available in three retail models (17-inch, 1.6 GHz is M9363LL/A; 17-inch, 1.8 GHz is M9249LL/A; 20-inch, 1.8 GHz is M9250LL/A) plus one education-only model that has no optical drive, no modem, and a more modest GeForce MX4000 graphics system.
* May 3, 2005 — Apple releases "Rev. B", or the “Ambient Light Sensor” line (the name refers to a new light sensor on the bottom of the iMac that adjusts the glow intensity of the white pulsating sleep indicator light according to the ambient light). The entry model is now 17-inch, 1.8 GHz (M9843LL/A). The mid-model is 17-inch, 2.0 GHz (M9844LL/A) and the top model is 20-inch, 2.0 GHz (M9845LL/A). All models now feature 512 MB of RAM standard; the hard drive capacity is increased to 250 GB on the top model, with an option of 400 GB. Optional upgrades now include a double-layered 8x SuperDrive. All models now feature Airport Extreme wireless, Bluetooth 2.0+EDR, and an ATI Radeon 9600 graphics chip with 128 MB of VRAM as standard. Also the 10/100 network interface has been upgraded to 10/100/1000. All models now ship with iLife '05 and Apple's new Mac OS X v10.4 “Tiger”.
* October 12, 2005 — At the “One More Thing” event, Apple released new iMac G5s (the "Rev. C", or the "iSight" line); a 17" display running at 1.9 GHz (MA063L/A) and 20" display model running at 2.1 GHz (MA064L/A) with:
o A built-in USB 2.0 iSight camera
o A remote control called Apple Remote
o 512 MB PC2-4200 (533 MHz) DDR2; expandable to 2.5 GB total memory
o Slot-loading 8x double-layer SuperDrive (DVD+R DL/DVD±RW/CD-RW)
o Mighty Mouse
o A PCI-Express ATI Radeon X600 (Pro for the 17" model and XT for the 20" model) graphics chip with 128 MB DDR VRAM
o Built-in media center software called Front Row
o Horizontal input ports rather than the less stylish vertical configuration.
o Thinner 1.5 inch (3.8 cm) flat panel housing with a curved rear housing
o Note: the built-in V.92 modem was removed and is now offered as the optional Apple USB Modem. The USB modem is available on the Apple Store website and also in Apple Retail stores.
o In February 2006, Apple discontinued the 17” iMac G5 and began solely selling a 20-inch iMac G5 for $1,499.
o The iMac G5 was completely discontinued in March 2006.
Good luck and please let me know if this is what you wanted,
