This is a real nice workstation. This Dell Precision T3400 Workstation was professionally maintained in a tech savvy law office. The computer was refurbished prior to entering the market place. Windows 10 Professional, 64 bit, keeps everything running smooth. The hardware begins with an Intel Core 2 Quad, Q9650, running at 3.00 GHz. Sixteen gigabytes (16.00 GB) of memory gives your software plenty of room to run. The memory fan and shroud keeps your memory operating at an optimal temperature. The operating system is installed on a 120.00GB Solid State Drive (SSD), while your date is maintained on a 1TB Western Digital RE Datacenter Hard Disk Drive (HHD). An additional, vented hard drive cage is also installed in the tower, providing room for at least three (3), 3.5 inch hard drives. The solid state drive is installed in one (1) of two (2), 2.5 inch bays. An integrated SATA controller supports R.A.I.D. 0, 1, 5 and 10. Dual monitor support comes through the dedicated Nvidia Quadro FX 1800 graphics card. Also included is a DVD ROM and an integrated Broadcom 5754 Gigabit Ethernet controller. Power comes through a 525 watt power supply. I am also throwing in a free power cable and two (2) DisplayPort Cables. While this is a refurbished computer, it does have some very minor blemishes, but these are strictly cosmetic. The computer has been through a battery of self diagnostic test and is fully functional with the latest updates, drivers and BIOS.
