Looked - but can't see any - last one was in late April. But some members do titles such as 'Clear Out' - and i haven't got time to check content of ambiguous titles - loads of them. So there could be other for sale.
However, there is a separate wanted forum where you can make requests - and suspect you would get a positive response if you asked if anyone wanted to sell a z77.
Get posting on the general discussion forum if you miss out in this board - seriously - it won't take you long to get the 1000 that you need.
Or comment on some Project Logs - just don't spam indiscriminately.
Project Log forum is excellent for browsing if you like building PCs - i rarely comment but enjoy looking at quality, enthusiast builds.
