for half the price and then have to get all the software that would comp with a normal PC illegally

... plus you dont get any tech support jus in case you mess up your system

..
Anyway... as far as i know.. celerons are TERRIBLE for gaming.... my p2 398 mhz outperformed an 800 mhz celeron with a better vid card by a lot.. i got 2x as many frames per second while playing on a higher resolution ... so thats a pretty big performance difference...
But.. if your not doin any gaming and only use it for like burning cd's and word processing and stuff like that i guess go wih the cheap celeron.
How bout like an Athlon or a Thunderbird or maybe eaven a pentium3?.. i jus despise celeron processors...
