I'd say practice soldering / recapping using random wires, dead motherboards and the like, that's how I started not too long ago.  A year down the road, though, I don't think I'm ready for doing my own recapping on machines I care about.  My biggest project yet was modding an early Amiga 500 to 1MB ChipRAM and Kickstart 3.1 (not as easy as later models), and I just about had a nervous breakdown soldering on it cause my motor skills suck.  And those were significantly larger targets than you'd deal with in a recap.  Sucks cause I have a lot of gear that is either going to need recapped soon, or is way overdue.  With a low operating budget (part time college jobs, woo) the only realistic choice is to learn to do it yourself.

What I'm saying:  You'll need a hell of a lot of practice if you want to sure you're not going to harm your lovely new machine.  Don't jump right to the hard stuff or a lot could go wrong!
