well while installing leopard my 1.4 year old iMac 20" crashed and the apple store says its the logic board. no warranty, thought my mac would last at least two years without failing. anyway, i dont want to pay $982 for apple to put in a new logic board into a mac that isnt worth that much now. i want to know how i can find out exactly what kind of logic board to get and some sources online where i might purchase one. any ideas about how much they cost? i need my specs but apple has my imac at the store right now. all i know is the following: 1) IMAC (Early 2006 20-Inch) 2) had 2 GB of ram 3) i have the serial number and sate of purchase but thats it. i cant boot it up to see what it says under "about my mac" from the apple drop down. PLEASE HELP!
