Absolutely!

I'm not a fan of financing. Except if you can afford it right now, but the financing just makes more financial sense. For example when you pay less interest than your savings earn you. (seems unlikely though)

As for whether you should buy an iMac Pro at all, that also depends on personal circumstances. Your current setup, etc. Hard to provide advice without knowing those details.

Amazon has had an amazing deal recently with 0% financing for 5 to 6-months but I'm not sure if it's only available in the US or not (just throwing that out for anyone considering it) on most of the Apple lines right now.

That said, if you can get financing for less that 4% to 5% then I think it's a great investment in yourself.
