The one thing I noticed was the temp sensor placements, that's about it to a certain extent I can see as far as the LoBo standoffs themselves-- past that, I want to know why I'd have to get a new inverter cable. IIRC the only reason I can think is someone saying a cable from the inverter goes to the wireless card-- which wouldn't make any utter sense unless it was to add a third antenna for a tri-antenna MIMO card instead of the BCM94321 cards used in some models. My mom has a Late 2007 model with the 4321 I dropped in from a Dell, uses both the original 802.11g card's antennas just fine and hasn't had a single problem. I have a small cache of 4321's I can make use of that are out of Dells and other macbooks that'll just make everything work out for that, but sheeeeeeesh.
Another thing I'm seeing is the addition of the PRAM battery now being housed under the lip of the Superdrive on the right-hand side of the bottom housing, out from under the 2006 model's location under the LoBo. probably because of the board revise they didn't have the ability to hide it under there anymore. This then also requires you get the newer speakers, and the right speaker assumes two standoffs, oen in the same first-mount location and the other doesn't exist on the 2006 housing. At this point it'd be easier to just get a bottom housing with board/heatsink/fan from a mid/late 2008 model and drop all my existing parts on that aren't the board.
Right now I MUST replace the logic board as it's no longer charging the battery at all, and it doesn't make either of the Magsafe chargers I have which are known good light up when connected... but it'll still apply power to the port and board allowing it to turn on. if I could figure out that problem (already tried resetting the SMC, any other ideas?), I can go right ahead and swap the board with this late 2006 white one I have sitting here which is another of my mother's Macbooks she's taking back and forth with her to her job so she doesn't have to care if it's stolen. She only needs 10.6.8, so the T2500 board in the blackbook would do her more good than the one with the 1.83 Twhateveritis C2D that won't be doing 64-bit stuff anyway! Doing that swap would be a walk in the park because of how minimal the difference in the logic board and connected peripherals there is. it's insane. it'd at least make for a good stop-gap until I can do some proper not-so-rushed research into anything I'd have to do to get it running as a much newer version of itself. and with the small abundance of these logic boards up on eBay and elsewhere, it's not hard to find them if so necessary.... I just don't want a Core Duo. I do NOT want a Core Duo. it has to be Core 2, and it has to be 45nm, hence why the 2008 models are what I'm shooting for. From what I understand and know of from experience in modern PC laptops from that time, a 65 to 45nm upgrade drastically improves upon the efficiency of the heatsink it's contacting since there's less contact area to work with, so the heatsink is actually a little bigger than it originally was for its intention to be used on a 65nm chip. As I've never used used a 45nm Core 2 Macbook for more than 5 minutes I can't necessarily attest to that being the case with them, but I can at least dream.
