Cheers, had a bit of an intermittent boot issue, sometimes it would boot, sometimes it wouldn't and would just beep 4 times (Bad ROM Checksum). Some contact cleaner across the CPU card connector seems to have cleared that right up. Running like a dream now, but still subject to improvements. Will be installing the AirPort card soon, along with the added RAM and the bigger/better HDD, need to adjust the focus pot on the DVD-ROM drive and fix one of the tabs that locks the keyboard into the body as well as it's come loose. I'll seek out some replacement black rubber feet soon as well. Already replaced the thermal compound on the CPU as the old stuff wasn't transferring heat well.

Battery is completely dead, may have to try and re-cell it later on for added mobility.
