Zip Drive Question:

An internal zip drive is always going to occupy or need a 3.5-inch drive bay. If no 3.5-inch drive bay is available, the computer needs a drive bracket and partial front bezel to cover the empty portion of the front of the Zip disk drive. Drive brackets are included with the internal zip disk drive package. If your computer does not accept the drive bracket you may want to consider any of the below recommendations.
Contact the computer manufacturer for drive brackets compatible with your computer.
Visit a local computer store for alternate brackets.
