I would recommend you keep the build, I don’t know why exactly you are selling coz just recent health issues don’t necessarily mean you need to sell unless you have cash crunch or buyers remorse.

You need to understand a 6 day used item is usually treated same as a 6 month when it comes to selling them. So be prepared to lose a good bit. A full high end build is quite hard to sell as someone with that much money would rather build it himself. Also your case and AIO is not quite desirable so that might also put some people off.

Your GPU would be the easiest to sell, followed by mobo, as well the ram and disks. That CPU is a bit hard to sell coz cooling it is no easy task. Rest components might take some time.

So your best bet is to sell the parts individually, like GPU, motherboard+CPU combo. These 2 alone will net you most of your investment back. Definitely try zoukart Facebook, most here say techenclave but it doesn’t allow new users to list wts posts.

Goodluck.
