No, I'm not putting the motherboard together, or someone here is misinterpreting something. The motherboard is ready, it's in the case, so is the PSU, I'm connecting the hdd and DVD drive.
I couldn't find the SATA ports on the motherboard at first, and each device is now connected by SATA cables to the motherboard. Since both devices are SATA, and I have them both connected to the motherboard.
