Well, still the same for video rendering having around 12-16gb of RAM will make rendering faster.
The same should apply, you shouldn't need a solid state drive and bumb the GFX card up to a 770 like this one: http://www.pny.eu/product/p-7-220-693/Overclocked-Series/GeForce-GTX-770-XLR8-OC-PCI-E-2GB/ but obviously you mightn't have the budget for an OC edition card.
Anyways, happy picking
