Im building my first pc and ive gotten to placing the mobo in the case. the hardware that came with the case only includes 2 motherboard standoffs (none missing cause it says x2 in the manual). Am I supposed to have more standoffs in the mobo box or something? There is also something that looks kinda like a standoff preinstalled in the case. The case is a Cougar Solution and the mobo is a Gigabyte 78LMT-S2P. Thanks!
