As long as you're running 8.6 or higher, you could put a generic USB card in the Mac and use an external USB CD (or hard drive or memory stick). It would save you having to dismantle the machines to transfer the drive.

You'll only get USB 1.1 speeds (12MB/s) on the Mac, unless you're using OS X via XPostFacto. And you'll need to download and install USB drivers under 8.6/9.x
