The sky's the limit with building a "keezer", which is what you are going for. You can frame a cabinet around any chest freezer, regardless of size and use any wood you want. Some go with high end hardwoods like cherry, while others like me went with a rustic look using knotty pine and cedar logs. You do need to leave a 3" gap between the outer skin of the freezer and the cabinet to avoid overheating, according to most manufacturers. On the other hand, I have seen some builds where the guys glue thin wood paneling directly to the outside of the freezer and claim to not have overheating issues. Your search for "keezer" builds or looking a JuanMoores "coffin keezer thread" should yeild you plenty of ideas. Let me know if I can help! Good luck.
