Just got this from a client of my company for free. Chassis/case + mainboard. No memory, drives, etc. Powers on (good battery) and screen works, so I figure may as well get some parts and get it running. Are hard drives universal as far as notebooks go? I'm about to take the hard disk from my HP laptop and toss it in the Tecra, then go from there. Is it difficult to operate on notebooks (I'm very familiar with taking apart PC's)?
