Minecraft on Dell Optiplex 745 mini tower?

I found one on ebay for about $80… My budget is only $100 because i'll mostly use this for school and i'm not a super gamer but I just want 1 game which is minecraft to build and chat with my friends after school.

Intel Core 2 Duo Processor - 2.13 GHz ( is 2 ghz good or 3 ghz?)
Intel Q965 (ICH8) Express Chipset
2 GB Ram ( i might upgrade this to 4gb or more later )
160 GB Hard Drive
Win XP

btw i will put everything on the lowest setting will the game even open? I don't need fancy graphic

Bit old but not hopeless it has core duo and should be decent enough
you will def not get minecraft to work on its graphic though but easily make it into a cheap gaming rig once you upgrade ram to another 2gb believe its ddr2
you can use a program called speccy to check if you buy it

with these add ons you can get low medium spec

sounds like a good deal to me anyway and the above upgrades will allow you to game
