What works:

Everything is works great on this machine. It boots in 36 seconds. It has a 60 GB laptop SSD as operating disk and 150 GB HDD second disk.
With this machine I have learned to mount disks to use for steam games.

PC is 10 years old now.
It's given a new video card this summer. On this card I connected two very large 27 Inch flat panels to work on.

What doesn't work:

Can't think of anything for now.
