"Tell me about your IT setup at home" is my favourite interview question, followed up with "And what are you planning next?". I've been using it for years now, and it's been an excellent assessment every time.
It lets people talk about a technical area that they're super-familiar with, and also lets them show how they think about planning/purchasing/budgeting. It's also weeded out people who really aren't at all interested in computers - this is fine for some roles, but for most, I want someone technically-focused.
They can sell H100s for tens of thousands of dollars, and there's a multi-month queue to buy 'em.
