Marc, I usually don’t work with MDF, but I don’t see why your project won’t turn out great using it. The great thing about using MDF is it doesn’t matter about grain direction, so you can maximize your usage on each sheet. I would recommend you edge the front edge of each shelf with the 1 1/4” strip.(MDF would work fine) Since you are going to paint it, you can glue and nail the edging in place and when you sand it, the seam should pretty well dissapear. The one thing to remember about finishing MDF is the end cuts are very porous and will soak up finish like cracy untill it’s totally sealed. When you finish, use a good primer first to seal it completely and sand it before you apply your final coat. You should be able to finish both sides of the MDF to look the same if you lighly sand all surfaces and prime it first. You can use pocket screws with MDF, but you have to be really careful. Make sure you glue each joint and be very careful when running your screws in. They will tend to pull in too far and pucker the area around the head of the screw. Run your screws in slowly and only pull the joint together just enough to make it snug. I would recommend you play with a couple pieces of scrap MDF first to get the feel of what can go wrong when working with the pocket screws.
