I think you have done well if you bought it right. Now re the pc. first I would re-seat the cables to the hard drive and re-seat the ram as well. Before you start loading a new operating system try putting the drive (as a second drive) in another pc to see if you can recover any data from it like the XML file from the Mach3 folder as that will contain all the settings ect.

Bearings blocks you can buy the bearings (they should be AC bearings 2 No.) they should come out quite easily notice which way are fixed in there (ie back to back or front to front) the bearings will have numbers on one side to identify them. They also might have a shim between them.

The bearing block is known as a BK type It looks like a BK15 and the other end of the screw a BF type if it is floating.
