So, I managed to get myself an m17x r4 from the dell outlet with the help of Adam182 
since it was quite a bit under my budget, I have some money left over to spend on some accessories
I was wanting some opinions on:
A laptop rucksack that will fit the laptop and some books for school along with the charger and a mouse, preferably waterproof.
A laptop cooler
and
A 3.5" external hard drive caddy that is preferably usb 3.0 and powered by usb (not sure if you can do this)
Can you guys help me with these?
