You might want to consider the Corsair 200R over the 100R as the former is superior, imo. (Although they should have gone with a single 5.25" external bay instead of three. Like the In Win 703 (which I would never buy because it doesn
t allow the mounting of a top mounted fan.)) You should do Google searches for any case you're interested in by search for the name, model and the word "review". Trust me, choosing the right case could be harder than choosing all the other components.
I would suggest you also get an anti-static wrist strap and watch a YouTube video on how to correctly use it, although the printed instructions should be sufficient. Basically you find a work area that isn't conductive, like a wooden table top and make sure that you're not standing on carpet, it should preferably be tile or wood. When handling electronics, especially RAM modules, you do not touch the gold fingers, you do not touch the chips, you do not touch the board etches. With RAM you use your thumb and pointing index finger to hold it length wise and insert the modules down into the slot. (Ever wonder why some mobos tout anti-static circuitry for the USB ports? Yep, you never want to touch the metal guard on USB devices, especially as you insert them into the USB slots.)
Noctua's instructions call for ~ 1/16" sliver of thermal paste be applied down the middle of the CPU top, which may work fine for dual cores, but I went with a "+" pattern - no the thermal line does not extend all the way to the edge of the CPU case, it should stop about 1/4" from the edge.
