This is a supremely upgradeable, reliable, and robust workstation that will handle whatever heavy-duty tasks you throw at it. Add more SSDs (solid-state drive) to really speed up this beast. Further upgrades could entail USB 3.0, more powerful graphics cards (could easily run several video cards), faster SATA, second optical, or another drive (the machine can run internally 6 drives). You get the idea. 320 and 500GB Internal Hard Disk Drives CPU - 2.8 GHz Dual Quad-Core (8 cores) Memory - 22GB OS - OS X High Sierra Video - ATI Radeon HD 2600 XT 256MB Optical Drive - SuperDrive CD/DVD RW Delivery could be possible... I don't need to delete the software loaded on this machine (most high-end graphic, and audio)... *stock photo
