I'm no expert but,...do you already have the board? It's a micro mobo. Is that what you want or need?
Do you already have the heat sink and cooler. Why did you pick this cooler rather than say a CoolerMaster Hyper 212 Plus?
Do you already have the RAM? Some of the users here think that a lot of the heat spreaders on RAM are more for marketing, decoration or looks. Some people think they're unnecessary or not really that functional. There are ram sticks without heat spreaders that apparently work just fine. It's a debate
I think that with most mobo's you alternate the ram sticks in the slots. If you're just using 2 sticks, you either you put the sticks in slots 1 and 3 or slots 2 and 4 . What brand and version of RAM are you using? Do they have tall heat spreaders on them? Are they really necessary?
Good luck.
