This is an older HP 2 core computer but it looks like it is totally new inside and out. It started right up and loaded Windows XP Pro from the supplied "golden" disk for refurbished computers. The disk included XP updates through sp3. Another nice feature is no "free trash-ware" offers preloaded.
I added a DVD R/W drive, a 750 GB drive and a USB wireless LAN adapter from my old computer. The computer is in my barn about 400 feet from my house and everything works just fine.
I'll be back
This computer, although old, fits perfectly within an established home network without dealing with issues of different OS or needing to get new/upgrades to applications or tools. The internals were all upgraded, plenty of memory and fast CPU. Comes with a 1G ethernet for fast networking.
