OWC tempts with 4-bay Mercury Rack Pro RAID solution

If OWC's latest and greatest external RAID drives are just too, um, unmountable for your tastes, how's about this? The 4-bay Mercury Rack Pro features the increasingly familiar quad interface (USB 2.0, FireWire 400, FireWire 800 and eSATA) and supports up to four 2TB 3.5-inch SATA I / II hard drives, up to 128MB total data buffer, a variety of RAID options and ultra-quiet operation. Those looking to fill that one last 1U slot with oodles of storage room can buy in now for anywhere between $899.99 (2TB) and $1,499.99 (4TB).
