I mean, you probably need a computer. You could use your personal machine for a little bit, but if something happens to it (stolen, damage, etc) good luck convincing your boss to replace it if they are stingy with money.

I would probably spend 1500 on a computer the first year, and then maybe a used Herman Miller chair if you can find one. That would be an amazing bang for your buck. Next year, you'll have a lot more wiggle room to play with. Finally, check with your boss about purchasing gift cards with your excess stipend to use next year. If they will let you carry it over then that won't be necessary.
