I've probably bought MS Flight sim before, and perhaps some other games. I prefer their mice and had a sidewinder joystick.
I consider Windows to be roughly the halfway point between ease of use and open architecture, with Linux being very flexible and Mac being extremely inflexible.
Turns out my tower idles at about 35 watts. It has an
i5-3570K quad core processor.
It has 8GB RAM, and I'd probably put my smaller 128GB SSD in it.
I've also got a Lenovo G410 I could probably part with. It was the last computer my grandfather bought before he died 3 years ago. It has an i5-420M CPU and 6GB RAM. It has a 120GB SSD. I keep thinking I need to fire up MIRC and see if anyone is wondering where he went... but it's been 3 years now.
