Just scored an amazing deal on eBay for a 4,1 , so so excited, to put it into work and setup my studio properly. My Digidesign 002 arrived today too, so i've got more stuff to add into the rack! Code: Exceptional specification Apple Mac Pro for sale in superb condition. The Mac Pro has been updated to the latest version of Maverics (ver 10.9.3) and everything has been tested and configured. Here is the long list of upgrades included: 1) Memory has been upgraded from the original 3GB to 12GB, using 3 x 1066 MHz DDR3 EEC 4GB memory modules for optimal performance. 2) The CPU has been upgraded from the original 2.66 GHz to a 3.2 GHz Intel Xeon Quad Core processor for excellent performance. 3) An Apple Mac Pro RAID Card A1247 has been installed to offer improved storage performance and data protection up to 553MB/s of sequential read performance in RAID 0. 4) Two 7200RPM 2TB Hitachi Deskstar hard drives have been installed in a RAID 0 configuration for superb data protection. This replaces the original 640GB hard drive. 5) An original Apple Airport Extreme Wireless N WIFI Card has been installed to add flexibility. 6) An internal Pioneer Blu-ray reader and burner has been installed to support backups and large data distribution. 7) A Sonnet Allegro USB 3.0 PCI Express card has been installed to provide two high-speed ports for the latest external storage devices. Thats the eBay auction. Its also boxed and has all its disks etc! Not sure what to do with the Apple RAID card, are they worth anything? I paid £750 UK for the machine, which is a pretty damn good deal.
