You'd have to get it with a dewer, you couldn't just store it in a fridge
But it's so much colder than LN2, that most motherboards break when using it (even if you try insulating them).
Also, it boils very very quickly, I've seen a general idea that 250 litres gives you 90 minutes of benching time (250 litres is one of those big dewers full).
For where to get it, universities will have it (not sure if they'll sell it to you), or specialist engineering or laboratory suppliers will have it
However, as others have said, I'd advise against using it... Unless you are actually going for world records (and think you can achieve them), and are experienced at handling and working with liquid He4, then just stick to LN2
