Very wise advice - too often we overlook this form of "recycling."
Keep your old computer. Get rid of everything but the operating system on it, and use it (networked to your main one) as a storage bin for the photo files. Turn it off when you are not transferring files to it. That way, if a virus or a power spike hits your main machine and takes it out, it won't affect the (turned off) file storage computer.
