You might have better luck posting in the computer hardware section:
https://bitcointalk.org/index.php?board=75.0Not too many people in these parts are super familiar with Bitcoin miners. It will be a difficult sell because you'll have to find someone collecting old mining hardware as it is no longer useful (why I understand you posting it in this section) but I'm sure there's someone out there looking for display pieces as a reminder of their time mining Bitcoin back in the day. Good luck!
