Hello My friend acquired a functioning HP Compaq 8200 Elite Small Form Factor. He needs to swap out the HDD and get a fresh new install of Windows 10 which he is doing. But he also wants to look at upgrading other parts and making it an entry build. I decided to help him out. I read about the PSU and the Motherboard. The board has an AT connection and the PSU only pushes out 200w. I made a small list of parts that fit in allowance of the systems case. Now the problem is; is the board doesn't have the proper connections. Does anyone know of a board that will fit? Also I believe it is a micro ATX board I am not sure though. I will try to find a board as well that has similar mounting holes. Much thanks:)
