How to build a computer

Hi,

My Dad passed away last month, I've been sorting through his stuff and I've found what I think are alot of the the makings of a new computer.I know he had a very old computer model that that he'd wanted to transfer onto a new one to preserve his files for years There's a tower and loads of various parts set to one side. I would love to finish what he started as I know it was very important to him. But I don't know where to start, I have no idea what half the stuff are. I'm going to list some of the items here, and you guys may know what they are for, or if they are relevant to building/fixing a windows pc. Sorry I know this is a long list, there is actually even more, I'm not sure if his plan was to replace the parts in his old computer, or build from scratch. Any help would be greatly appreciated.
