Whether the equipment receives a CD in MP3 format? What color is the minitower CD? What power has the speakers? How many CDs can be inserted at once to the minitower? I really like to listen to the radio. Is it included? I also have a few tapes with interesting songs. Is it the player to the tape? I have a small commode on which I would like to put this tower. What is the size? Is it serious?
