along with the motherboard, you're also going to need the cardcage/heatpipe system as well. if the mainboard doesn't come with the primary and secondary fans, you'll need them too, they're more powerfull and radial discharge, not axial. there's a bracket for the heatpipe on the power button side as well as some foam necessary around the fans for proper cooling (fan to case sealing). you can make some thing to fit if you don't have the factory stuff, it's looks pretty simple. so the easiest way to upgrade is get a trashed tibook. the 800 and the 1ghz have the same interior rib frame and cases etc. in any case (hyuk hyuk!) good luck! -Jason Economou Carbotron Composites kradcarbon.com On Aug 10, 2005, at 6:22 AM, Susan Rennie wrote: At 3:50 AM +0200 7/12/05, zefred wrote: > Well, I boosted my Ti800 with a new 1Ghz motherboard (the old one > fried suddenly after I overclocked it to 933Mhz...), 1 gig Ram and a > 60Gb 7200 rpm hard drive, and I can assure you all of this gave it a > second life. I would like to replace my Ti800 motherboard with a 1Ghz. Could you say where you got the motherboard and whether you replaced it yourself or is it possible to have Apple do this?
