Custom-built old Desktop PC for music production

I built this PC for my music production studio 15 years ago but I haven't used it for several years. I specifically built it in such a way that I can connect lots of midi devices (DJ controllers, mixers, midi keyboards and pads) so it has 10 USB 2.0 ports in total. I was able to install Windows 7 Pro into this machine but unable to upgrade it to higher versions. This DOES NOT include any Harddrives or SSDs. Also, I haven't replaced the CMOS battery so sometimes it doesn't remember the current date/time or previous BIOS settings. Buy this if you need parts or if you want to build an older PC.
