Parallel ports and motherboards

Im a slacker yes. but the 2nd last time I bought a bunch of barebones computers for work they didnt have parallel ports, then this last time I bought barebones computers they DID have parallel ports but the case was WAY WAY bigger than I had room for so I had to shuffle the guts into the older slimline cases....... any one have a nice time saver for me I have been doing a little digging but not really getting the results I am looking for. I need a slim line case with a mother board with parallel ports. HALP!!!!
