Recently my Dell Precision 390 just stopped working. I'm fairly sure the motherboard is the issue, so I want to replace it and salvage the processor and memory. The problem is I don't know a compatible motherboard I can get to replace the old one.
As both the Precision 390 BTX case and motherboard have proprietary features, you need another Precision 390 BTX motherboard, there are no third party retail motherboard equivalents available.
