Motherboard needs to have enough drive connections
I recently bought a cool case for my new pc build. The wow factor on this case was the number, type and style of drives it could support (4 open bays, 4 SSD slots, 2 SATA slots, and 2 hot swappable SATA slots). Unfortunately, once it was all delivered, I found that the number of SATA3 ports on my motherboard was less than the number I needed. Now I have to purchase another pci card just to be able to connect all of the hard drives, SSDs, DVD drive, etc. I'm new to building PCs from the ground up, so while I thought I'd crossed all my t's and dotted all the i's, I still missed this rather obvious caution.
