My Precision 650n Work System

It's a bit too rich for my personal purchase, but sure beats a Sun Workstation in performance and lower cost.

Front of computer Front view of system with drive access and accessory connection doors open. The latter has microphone and headphone jacks, two USB2.0 connectors, and the diagnostic lights. The light grey "shield" that covers the vents has the word Precision written all over it, which can be seen in the enlargement. The stickers are for Xeon which while much more expensive than a Pentium 4 is cheaper looking, and for "N" - no operating system, I guess. Click on the image to enlarge.
rear view of computer The back view shows the connections for two serial ports, parallel printer port, integrated sound, PS/2 mouse and keyboard, USB 2.0 (4), firewire, gigabit ethernet, and video card's two DVI connectors as well as the RAID controller's exteral SCSI connector. Like the Dimension XPS, the power supply is at the bottom. Click on the image to enlarge.
inside the box The 650 opened up. the shroud covers the two Xeon processors and exhausts through two temperature controlled fans out the back. The video card has a separate power supply connection but no fan -- there are heatsinks on both sides of the card. The four 1GB sticks of ECC RAM are readily visible. A large baffle separates the card cage from the rest of the system when the case is closed. A separate fan cools all the cards while the memory and drives are cooled via the air that gets exhaused through the processor fans. Even running full blast on both processors, the system is quieter than the 1GHz Pentium III "white box" system I still use for Windows applications. However it does warm up the office!

inside view toward drive bays From this view you can see the back of all the drives. The SCSI cable has connectors for four drives, the maximum allowed in the case. Click on the image to enlarge.
