I know that I need to find the books and whatnot to study for the exams, but what kind of hardware will I need to run the software and programs that I'll use to implement and learn the things taught in the book? I use a VERY crappy 5 year old laptop (clock speed 800mhz) with only a 10GB hard drive. I'm assuming I'll have to purchase a modern computer to install and run Microsoft Windows XP Professional (for the 70-270) and Microsoft Server 2003 (for the 70-29x series)? Any help you might have on this forum would be greatly appreciated.
