Yes, a Dimension 3000, shipped 3/8/2005.
The previous owner [a non-geek kid] had installed a 2nd stick of 512mb memory to bring it up to 1g. He also had installed some kind of gaming video card, but I'll know more once I dust it & attach a monitor,etc.
Depending upon what it is going to be used for, 1GB of memory may be plenty with WinXP. If you decide to upgrade, you'll need to get PC2700 or PC3200 modules (184 pin DDR modules in DIMM format) - it only has two memory slots, so you'll have to replace both modules if you want to get to the max memory supported of 2GB.
If you have any problems installing a more modern hard drive, you might want to look at what BIOS is installed as it is probably way out of date.
Prescott CPUs tended to run hot, and Dell used a special proprietary CPU cover shroud that served as a heat tube to route the hot air outside the back of the case. If the CPU has a shroud, make sure to open the hood up (it unclips and folds open) and check the heatsink to make sure it is not filled up with dust.
