2 Mac Mini A1176 units, both functional and will turn on but display the question mark folder indicating there is no operating system installed. Could be a simple enough fix, I just don't have the time or patience to create the bootable installers and troubleshoot the issue, hence listing them as parts/not working. The mouse and keyboard are in full working order and in incredibly good condition for their age. Power supply also doing it's job too. There are also 2 display adapters included, I'm not entirely sure if these work or not as I connected both macs to an old Cinema Display that didn't require the adapters. Both have Intel Core 2 Duo chips, 80gb harddrives and 1gb RAM.
