JUST TO LET ANY POTENTIAL BUYERS KNOW, I AM THE SECOND OWNER OF THIS COMPUTER. IT HAS BEEN USED AS A RECORDING STUDIO COMPUTER FOR ITS ENTIRE LIFE. IT WAS ORIGINALLY PURCHASED FOR A WELL KNOWN STUDIO IN SOUTHERN CALIFORNIA, & I PURCHASED IT FROM THEM 3 YEARS AGO. IT IS STILL IN PERFECT WORKING ORDER, AND UP UNTIL I WIPED THE DRIVES AND DID A FRESH INSTALL OF EL CAPITAN. IT HAS BEEN RUNNING PRO TOOLS, LOGIC, CUBASE, REASON, AND MANY OTHER AUDIO PROGRAMS JUST FINE. THE ONLY REASON THAT I AM SELLING IT IS TO UPGRADE TO A MAC PRO THAT HAS THUNDERBOLT PORTS, AS IT SEEMS AS THOUGH THAT IS WHERE EVERYTHING IN THE AUDIO PRODUCTION WORLD HAS HEADED.

I HAVE TRIED TO DETAIL ALL OF THE SPECS TO THE BEST OF MY ABILITY, BUT IF I LEFT ANYTHING OUT, OR IF YOU HAVE ANY QUESTIONS, PLEASE DO NOT HESITATE TO ASK!

The Mac Pro "Eight Core" 2.8 (Early 2008) is powered by two 2.8 GHz Quad Core 45-nm Intel Xeon E5462 (Harpertown/Penryn) processors with 12 MB of level 2 cache per processor (each pair of cores shares 6 MB), a 128-bit SSE4 SIMD vector engine, and 1.6 GHz "64-bit dual independent frontside buses." Via custom configuration, this model could be equipped with a single 2.8 GHz Quad Core Xeon E5462 processor, two 3 GHz Quad Core Xeon E5472 processors, or two 3.2 GHz Quad Core Xeon X5482 processors.

By default, it was configured with 2 GB of 800 MHz DDR2 EEC "fully-buffered" FB-DIMM memory, a 320 GB (7200 RPM, 8 MB cache) 3Gb/s Serial ATA hard drive, a double-layer 16X "SuperDrive", and an ATI Radeon HD 2600 XT graphics processor with 256 MB of GDDR3 memory and two dual-link DVI ports.
THIS MAC PRO HAS 16 GB OF MEMORY INSTALLED, A TOTAL OF 4 HARD DRIVES, TOTALING 3 TB OF STORAGE.

Expansion includes two external 5.25" "optical" bays (one free by default), four internal 3.5" "cable-free, direct attach" hard drive bays (three free by default), two PCIe x4 slots, and two PCIe 2.0 x16 slots (one free with one graphics card installed). Ports include dual Gigabit Ethernet, five USB 2.0 ports, two Firewire "400" ports, two Firewire "800" ports, and optical digital audio in/out, among others. Bluetooth 2.0+EDR is standard, AirPort Extreme (802.11g/n) and a modem are optional.

Compared to the original Mac Pro that it replaced, the Mac Pro "Eight Core" 2.8 uses a more advanced architecture with faster and more efficient processors with larger level 2 caches, a more advanced vector engine, faster frontside buses (1.6 GHz instead of 1.33 GHz), faster memory (800 MHz instead of 667 MHz), support for optional faster Serial Attached SCSI drives (with the installation of the Mac Pro RAID card), and two 16-lane PCIe 2.0 slots.
