I have a used ATXBlade rackmount PC blade with 5 empty motherboard blade chassis for sales (w/250w per blade). It has been deployed as part of my render farm nodes for over a year. I am selling it for $800 or best offer. (Retail for $1250). It supports standard ATX motherboard, hd and memory in each blade.
