She sold this about 10 years ago lol, and had no pictures. Are there any numbers,. or markings on the inside of the case, on the bare metal? I would almost like to say this was a generic brand, which used alien logos just as a marketing technique. The case Does look like a Chieftec Alienware case though, so that could be a place to start. I just do not recall that any of the official Alienware PC's had those dials in the front.
I do recall this thing had been upgraded to Windows XP, and was maxed with 2GB of DDR2, if that helps you put a date on it.
My best bet is a modded version of this.
