No-name ATX Midi Tower Case with 250W power supply. Don't try to use the DIMM slots, they only work with EDO DIMMs. Don't try to use DMA on integrated IDE controller. It probably doesn't support it. IDE controllers in Device Manager, but no DMA checkbox in HDD properties.
Sound quality is terrible, of course.
Don't complain, you have sound card almost free. IRQ Steering is not working, of course, so you will have two free IRQs, when you have no additional cards installed. Entire motherboard is slow. A system with P166, 64MB RAM and Intel motherboard runs Windows 95 a lot faster than a system with P200MMX, 128MB RAM and this PC-Shit M559. This motherboard has no stability.
