Is a used Nimble AF40 worth buying for resale?

I'd pass if the plan is a quick flip. The likely buyer pool is pretty narrow: it's proprietary storage gear, noisy, and not especially appealing to someone trying to keep a home lab quiet and cheap to run.

Someone maintaining an older Nimble system might want it for parts, but that doesn't mean a buyer will be easy to find. Check completed sales and local demand before treating 350 euros as a bargain.

First, verify the model and drive inventory. AF40 is an all-flash model, while the HF line is hybrid, so the description of 22 hard drives doesn't quite add up. Ask for the exact chassis model, drive part numbers, and a current inventory from the management interface.

Don't price it based on the drive count until you know what those drives actually are and whether any prospective buyer can use them.

The licensing situation needs checking, not guessing. There's a view that basic storage functions still work without an active license, but that support and InfoSight are unavailable. Confirm exactly what works on this particular system and what a new owner would need.

Also, don't assume the shelf can simply be used as a generic disk enclosure. The controllers and operating system are proprietary, which limits what you can do with it.

Factor in power, noise, and space even if you have somewhere to rack it. A cheap array can become an expensive experiment if it stays running for months while you look for a buyer.

For a resale, those same costs make it less attractive to home users. I'd only buy it for personal use if the experiment itself is worth the money.

If those really are older 1TB hard drives, their resale value may be limited by low capacity and uncertain remaining life. Get health information and the exact interface and form factor before counting on selling them separately. The details given so far are disputed.
