From Apple's web site (note this is a PDF file):http://images.apple.com/macosx/pdf/MacOSX_Windows_TB.pdf
"Removable media and devices
A variety of other removable media and devices can be used to exchange files between
Mac and Windows systems, including Iomega Zip disks, USB disk-on-key devices, and
removable (external) FireWire and USB hard drives. For best compatibility, these devices
should be formatted using the FAT32 file system, which is supported by both Mac OS X
and Windows. Mac OS X also supports the ability to read files from devices that use the
NTFS file system format."
So it would seem that if you can connect the removable drive to your Mac (note the lower case "ac" :-) then you can read the files directly in OS X.
If you cannot connect the removable drive you should be able to easily network the PC and Mac and access the files that way. The linked document also adresses networking.
Good luck with your new Mac and moving your files.
