I would love to see a roundup of small GPUs. This is fast becoming a market segment that, for enthusiasts, was neglected for too long. Now that we have more options, we're slowly working towards a tipping point where smaller gaming computers will become the norm. As single GPUs become more powerful, it becomes increasingly realistic to only need one in a system. And with only one GPU, for most gamers there's no reason to get a full ATX motherboard. mITX will be the next big thing in gaming, and some even let you overclock. You can still have an i7, still have 16 or 32GB of RAM, still use liquid cooling, all that good stuff. With a good liquid loop, or good normal air cooling and ventilation, there's little point in having all that dead space and wasteful extra motherboard real estate.
Full ATX towers which are heavy, hard to move and easy to damage, and take up too much space, will eventually largely become a thing of the past. Help us get there by showcasing what's possible with smaller setups, starting with what can be done with smaller form factor GPUs.
