Well, I would love to have this tiny little machine, as I only own an anciant PC that not even has a graphics card. And having to play Minecraft on the lowest settings at about 20 FPS is not that fun...
The PC I have is one of those smaller ones (not nearly as small as this Zotac machine ;-)) already and I kind of like it... I don't like this huge mid- or even full-tower cases, so I would love have a machine that is even smaller than the PC I'm using right now. And having this machine would also mean that I colud use my old PC to controll the CNC router I'm just building as well.
So this would be the parfect PC for me for those two reasons.
