in that other one the motherboard i fit sideways and all sockets and ports are then ported to the back panel via extension cables the graphics card sits in its origonal slot . usb,s and ethernet port use the origonal holes and the extra sound and dvi, hdmi ports are extended to a singly bracket on a spare pci slot .
it depends on the layout of your board if you can fit it in this way . you need a board where the cpu and ram will not interfere with the drive cage . you can just about do it bending the pcie extension cable at the most minimal position.
i will show u some pictures once i have fixed my camera for a better explanation. my phones one just don't cut it
