I know HP Cxxx boxes aren't strictly speaking classic, but they will be one day and peeps on here are likely to know the answer :-). I've got an HP C180 and want to fit some more drives, but I'm short of the plastic rails you use to fit them. The easy question is, "does anyone have any spare rails they can sell me," so I'll ask it anyway but I'm not expecting a yes <grin>. I suspect these things are like hens' teeth, and HP no longer make them apparently. So, plan B was to make some myself. I haven't examined one in detail yet, but making a mould should be pretty simple - all I need is some molten plastic and Bob's my uncle... Of course, I haven't ever actually tried anything like this <grin>. Anyone have any recommendations - am I mad to even try this? If not, I'll be after a thermoplastic with a reasonably low melting point (got to be able to melt it on a domestic gas hob![1],) which is easy to handle and sets to a flexible solid (plastic tie-wrap kind of thing.) Is this sort of stuff available to a 'consumer' in a suitable form (eg. chips or powder?) Plan C involves Velcro, but the HP's are so nicely put together it seems a crime to do too much of a botch job :-). Cheers, Tim.
