what type of case will I need for this motherboard?

Any case that can fit a standard size ATX motherboard. Check the case description to see what form factors it supports. Also make sure you get a case that has the length or depth large enough for any add-in cards, like a GPU, or a heat sink you might add to your build. Most mid-tower and up cases you'll find will support ATX form factor boards. Cheers

Which type of solid state hard drive should I look for for this motherboard? Which SSD is compatible with this MB? thanks in advance

I used a Samsung evo ssd 250gb. The motherboard uses SATA connections and so do all if not most ssd's. So u shouldn't have any worries as to what ssd u get. I recommend getting Samsung branded ssd just out reliability even though they are a little more pricey. In the end you are perfectly fine with which ever one you choose
