We were having a lively discussion about the popularity of various PC form factors in TR's staff chat today, and it occurred to me that we haven't done a new poll in a while, so here we are. We want to know what form factor you chose to build your last system around. Maybe you went tiny with Mini-ITX or even Mini-STX. Perhaps you're a midsize fan and went microATX. Or—like we imagine is the case for many TR readers—you stuck to the traditional path and chose a plain old ATX motherboard and case. Whatever the case may be, tell us about the size of your last system using the poll options below.
