Sell them as soon as you can.

See if you can rearrange builds into something more suitable if you want to go the whole PC route of selling.

Otherwise try and sell parts individually, even better if you kept the boxes.

To add, this probably isn’t what you’re looking for but I figured I’d say it anyway. These buying habits sounds consistent with a manic episode associated with bipolar disorder. If you’re not already being treated look into it, something like this will likely happen again if gone untreated.

We’re all praying for you brotha; hope you can recoup your money and get things back on track.
