Probably simple answer to this
Computer has just died - RIP.
Will need to get a new system but want to recover some info from hardisk. Where can I get a connector (or what type) for the internal hardisk if I remove it . Are there usb connectors available?
when the new machine arrives, plug the old drive it into that as a slave and copy all the information you need to your new drive.
It depends on the hard drive you have but you can pick up a dock with both IDE and Sata connections that connect via usb to the new computer.
Heres an example on misco theres quite a few others out there too.
StarTech Hard Drive Dock for SATA & IDE Drives
I have got a hard drive dock at work for purposes like this or anything else.
Hope that helps
