I had this build now for over 15 years and it switched over the time in different cases.
But for the last years its a Silverstone Raven what is pretty nice because the board is flipped to get no problems with hanging PCBs.
Back in the days Sony first Development Kit (playstation 1) was based on PC parts. There was different Revs from H2000 (two ISA boards), H2500 PCI and the H2700 (three layer ISA).
Over the years i had all, but stayed with the PCI H2500. It has attached drive H2510 what let you able start disc games over sdk. The Build has also a CD- Emulator from SN-Systems and an special IO Port for controller and memory card.
The P2B has great chipset to get all the boards working perfect on Win98SE.
As GPU i used a Geforce 256 what gives me no conflicts on PCI bus.
Feel free to ask if you interested about functions in detail.
Im happy to share this little different retro PC.
