Depends on what CPU/VGA You want to cool. But 5L to be sure. Tho, these 5-10L dewars are usually not so good as 15-20L. If You find a good 20L dewar, it would be a good staring point. Good dewar has little LN2 loss and You can have another run weeks after You fill it up.

Around how much would a good 15-20l dewar cost?
what should I look for in a dewar?
