I recently acquired a Macbook 1,1 (1.83GHz Core Duo) and have been doing a lot of work to restore it. I now have 2 newer Macbook Pro's and this Macbook. I'm considering selling one of my MB Pro's (I only have two because my job hooked me up with one when I started), and using the Macbook 1,1 as my home computer (for internet, music, coding, and maybe some light Photoshop work), but only if I can beef up the processor (I've already added 2 GB memory and a 320 GB HDD). What's the best processor/logic board I can get for the Macbook 1,1? There are some good deals on eBay for logic boards. Thanks!
