I bought this for my office loaded with,then, high spec components for running intensive creative enterprise programs. Would suit a similar user. Has 2 small Hard drives for system and light storage, I used externals. I have gone to a loaded Thinkpad with docking station to save space. The build was done using a Gigabyte motherboard MA790XT-UD4P and a Dark Knight EAH4870 DK/HTDI/1GD5 graphics card and was upgraded with AMD Phenom II x6 core processor and 12 GB GSkill RAM. Power supply is a 550W Rosewell performance unit. See pictures. System info shown. I have cleared the drives and cleaned the entire tower. All ready to go to new owner. This is the tower only The system is running Windows 7 Ultimate and a bunch of creative programs. I can show it to you hooked up to a monitor and working.
