I just read your thread about the back 'popping' off - did you manage to get a replacement? Had any problems other than the back plate? Do you know if the 400GB limit is both IDE and SATA drives, or if it's just IDE?
I originally posted a thread in hexus.hardware and Funstar replied that he has three and seems pretty impressed with them. Shame there isn't any decent reviews or a decent spec listing any limitations for hard drive sizes.
Cheers though, hopefully someone from scan might know something and reply
