So I am building a server to run as a file access, WDS, WSUS, Domain controller, DHCP, DNS, and Print server to play around and get some experience with for work so I can move on up, and here is what it is built on:
It is a Dell Latitude D620 1.6Ghz CoreDuo stripped of everything but the board RAM and Hard drive. With the server OS it was running at 85-100C even cleaned up and with new thermal compound because the stock heatsink was not working right, the heatpipes weren't transferring heat to the actual heatsink. with the Athlon XP heatsink and a random NB heatsink it idles at 25C and loads at 35C. not a bad temp change!
The main focus of the built is do what I want it to- while just sipping power 24/7. I will hook it up to the power monitor today to compare it to an Optiplex 755 E7400 system I will have under my computer desk that the D620 will sit on top of (will use the E7400 system if power consumption is similar as I can add a Raid Controller to it and make it a real File server with redundant backup)
Also the monitor you are seeing is an oldschool Lenovo X41 tablet (the one with the Pen-only touchscreen) that was being thrown away with about 35 others at work :D
