OK! Went out this morning and got the new computer. It's a Compaq Presario, 2GB RAM, 250GB hard drive, AMD something or another, and Windows Vista Home Premium.
Since it's incredibly powerful and very quiet, I have named him Rude-Computer.
Still in the process of getting caught back up with links, file moving, etc. But I've got the music going, so it's all good. :-)
