Marc, as George mentioned; I think the reason so many cars have vertical oil filters is so you can fill the filter full of oil before you reinstall it. When you start the engine after an oil change, you get instant oil pressure. I have a remotely mounted oil filter in my Pantera and find oil changes much easier than when the filter was in the original position.
Summit sells a dozen different remote filter mount ("relocation") kits but you can probably create a cleaner installation by choosing the individual components yourself. It just takes some planning.
