On one hand, I could shop around on the Net for a while, source suitable components to build a quiet pc, and have fun putting it all together.
On the other hand, the new Mac Mini range just got launched here. And apparently they'll dual-boot quite nicely (triple-boot is harder, it seems, but I'll still have my laptop for Windows stuff).
On the third hand, I have a spare monitor, keyboard, and mouse (only used when working-from-home at the moment).
Hmmm ...
