First time builders should go with Intel based system for easy assembly. slap it together and load the OS.
If you want to go the AMD route, be prepared to a multitude of questions for the vendor, PSU, chip rev, mobo rev, ..., then your off to download newest drivers for motherboard and devices. more hassle than its worth, you only save 20 bucks.
Also one huge problem with AMD

Even the most experiance builders can screw up a AMD CPU.
This does not even take into account overheating and causing damage to the core. AMD has a problem with manufacturing currently, they cannot maintain constant core depth and glue placement. many processors were shipped with the glue missing the core = very weak core, and high end HSF spacers that are too big and HSF doesnt touch the core or too small and crushes the core. You will see posts where people say "do not use spacers" this is why.
Intel is almost bullet proof, you cannot cook one if the fan was installed incorrectly or HSF was not plugged in.
Everything is built to Intel specifications not AMD, so you can expect the highest level of compatability.
Need a parts list?
ASUS CUSL2-c
Intel P3, your choice based onyour budget.
PC133 or PC150 SDRAM
any other devices you can drool over will work fine.
This will compete with AMD systems, who cares if you get 120FPS in quake and AMD gets 119. you cannot tell the diff anyway. as far as office performance. AMD has small edge, but who cares if you get 200+ FPS in MS word or it takes .002 seconds to close vs Intels .003 seconds. as long as your machine works great you will be very happy with what you build. performance will not be a problem above 800Mhz.
Go the AMD route and your asking for trouble if your not experiance in all the AMD problems, and how to avoid them.
