Apevia X-QBOII Black Case Review
 

You may be wondering, what happened to the layout? The motherboard has been flipped upside down to the opposite side of the case. Many pre-built manufacturers use this type of layout, and I like it. It allows for the CPU to be rotated to the bottom of the case where the cold air sinks, thus allowing for better cooling. And in this windowed case, the PCI and PCI-E cards also get rotated, so the exciting top part of the card is shown off, instead of the boring bottom.
