(FYI: this is the dual-drive external RAID enclosure) Before I buy I need to know about the noise level of this thing. Is it as loud as some reviewers say? More so than a typical external drive? Your feedback would be appreciated. And on a side note, how can Apple cool a 24" LCD, dual-core CPU, fast GPU (Radeon 4850) and a hard drive (in my new 24" iMac) and make hardly a whisper doing it, yet my current external hard drive fans make even more noise?
