wine refrigerator?

[keri]

Hi, I am new to this message board (and wine collecting) but I feel like I've learned so much already! However, I am still confused about wine storage. I am debating between a wine refrigerator and a regular wine rack. Can I store both red and white wines in the same refrigerator even though they should be served at different temperatures? I have no idea how these refrigerators work and I don't want to make the wrong decision. I appreciate any help!
