Hello all! Well, finally I think that my cube is giving up! I suspect that it is the DC/DC Board. The problem is that most of the time, that hard drive (OEM Maxtor20 GB) and the CD ROM (OEM CD/DVD) will loose power suddenly, sometimes recovering it after a series of clicks from the HD, but loosing it again after few mins. It is like it goes to sleep, but just the drives. I have checked the power gasket (it's OK) and it has a 15' apple display which is working OK. I have opened it twice and reseated the board both times, to no avail. Anyone has had this problem before? Where could I find a new DC board? Thanks a lot!
