Thermaltake Core P1 TG chassis won't take up much room on your wall
 

Thermaltake has developed an entire family of wall-mountable open-frame PC chassis with its Core P3, P5, and P7. The Core line's newest addition is the pint-sized Core P1 TG, a mini-ITX case that puts everything on display. The motherboard tray is made of steel and the transparent top panel is made of 5-mm-thick tempered glass. The case includes additional brackets and a PCIe riser cable that allows the graphics card to be the center of attention, maybe as part of a liquid-cooled gaming system.
