Tray Load question

I need the service manual. Serching high and low only gives me the slot load. I have removed the CRT completely and now I don't remember what the non standard looking cables are and go to.

My plan is to put the parts in a case and run it as a desktop for server use or something. A service manual is my most needed thing at the moment.

I saved the power supply too so I didn't have to all that fancy atx conversion crap.
