Hi, Can anyone recommend as replacement MicroAtx motherboard for my home Geovison setup. I have a GV800 card with four camera inputs. I have been using a “ASUS P4P800-VM - Onboard graphics - Socket 478 - i865G - Socket 478” for sometime. However my problem is the motherboard has now failed. It would be nice if I could find a low power solution to some energy as the PC will be running 24/7. Many thanks in advance. Steve
