My main system I consider my personal machine is an A4000T loaded out with just about everything you can do with it now. I use it nearly every day I am home for as much as I can. I love to tinker and tune it for relaxing.
My other machines, A500, A600, A1200, A4000D are all reference machines and used for doing testing on others boards I repair. They are in good shape, but dont get used for play at all. They have proudly been used to save many others machines though over the last year.
