The trouble with cheddar

So in the Seemed Like A Good Idea At The Time category, about a week ago I went through the cheese aisle at Costco and bought a lovely aged white cheddar approximately the size of my cat.

Been having cheese on crackers with every meal, and it is quite delicious, but the block is starting to get dry at the edges and there are only so many cheese-and-cracker breaks a person can take in a day... so I'm looking for options. What would you do with so much cheddar? Dip? Macaroni? The cheese is almost Parmesan hard, so I was worried it would get grainy when melted.
