Adding msata is not soo complicated, with propeer tools and manual from dell website you can do it with ease. You will need probably extra screw for assembling it on motherboard because im pretty sure it will be missing if you bought your system without msata preinstalled. Personally im using msata 80gb for OS and apps only and Im using my 1TB hdd for data. In case of Bluray drive I dont have any experience but i think that any decent bluray drive available on the market will be ok. You can also call Dell and ask for compatible model list.

Im working on latest Intel hd 4600 drivers on my AW 17 downloaded directly from Intel without any issues so far.

Overclocked i7-4700mq in Intel XTU utility by changing multipliers to 36,35,34,34, temps stayed at same level but i didnt notice any increase in performance in games. In benchmarks scores are increased by couple points only so its not a must. You can leave i7-4700mq on defaults settings.

it will support ddr3L only

im using cooler master u3 for my m17xr4, it works great, temps lowered 3-7 degrees
