I checked that, but its not. I guess Dell didnt think that many people would be upgrading and swapping cases and so forth. The layout of the whole thing is abit weird. The power and reset connectors are on the right side of the motherboard and the usb pins are at the bottom. On my old pc which had an asus motherboard the pins where all in one place in a straight strip where there were something like 10-12 pins, but not with this dell motherboard, they are all split up.
