The BitFenix Colossus Micro is a perfectly practical case. However, the components we chose to put it in are not. It was the perfect storm - we had on-hand an i7-4790K CPU and a Radeon R9 295X2. The question was - can it fit? Yes! Barely.
We knew from the start we'd likely run into some fit issues. Putting two CLC radiators in such a small case was going to be problematic. Just fitting the 295X2 in the case when it also used a vertical mount power supply was tricky. Most power supplies that have enough wattage for the 295X2 are too long. Fortunately the Corsair AX860i had sufficient wattage and left roughly 1/2" of clearance for the video card. Like I mentioned - this build was not about being practical. It was all about what we could manage to squeeze into the case. I had the 295X2 on hand, so it begged to be used. For science!
Before anyone comments that we should have used part X instead of Y, or Q instead of Z, know that this part selection was not aimed at practicality. Different use cases prefer different part selections. Maybe you don't need an i7. Maybe you don't need 16GB of RAM. Or maybe the 295X2 is a tad more horsepower than you need to play Minecraft. I chose these parts for a couple reasons:
