how can i get hands on experience?

Hey everyone..well, i noticed that most everyone agrees here that getting hands on experience is the best way to learn, but I dont know how i can do that. I dont really have the money to just go buy a bunch of computer parts, especially if i mess something up and have to try again. Any tips on what i can do? Thanks for the advice.

also old computers have many of the features of the newer ones. for example the ISA did not change. although you might not find PCI or AGP on the older ones, you could still open up your PC and look at them. you are not going to hurt nothing but your self if you do not experiment with the hardware and the software and do hand on and get some experiance. or else the certification is worthless.
Then you might want to get a Pentium 233-megahertz at a minimum then... since in a year XP will be also part of the exam
Once you've built, tore down and rebuilt enough, some things like IDE drive configuration, RAM installation, upgrading drivers, etc just come natural.
so good luck.
