One day, I took a plane up to practice some approaches. I knew I was rusty and I had an instructor on board. Even though I am an instructor myself, I knew I needed the practice to be proficient. That day was an especially bad day. I could not conduct any approach as well as I liked and while it is easy to chalk it up to rust, it really bothered me. I went home and promptly brought back to life a project I had been slowly working on...

I had a few computers left over from other projects. I immediately proceeded to cannibalize them for parts and in the end assembled a monster with enough power to run both FSX and XPlane reliably.
