This slimline from 2007 reviewed at http://forums.cnet.com/7726-19411_102-5107759.html might be brought back by popping in some short height video card but that's a gamble.
I'd move on and salvage a few parts.
I was not here, but while out of state my wife said lightning practically came thru the bedroom window. The video on the m2n61-ax motherboard(aka Dell 531s desktop) quit, I tried the monitor on another desktop & it didn't work there either, so the monitor got fried. I power up the 531s & it sounds like it goes thru bootup just fine, its just that I get no video thru any monitor. Apparently the lightning went from monitor to pc, which is strange.
Question is now - should I try another motherboard, try a video card(which I can't really configure), or do I just salvage what I can out of the pc and then toss it?. The video card idea would be the cheapest, but I don't know how to disable the pc from looking for the onboard connector since I can't see video now.
