Troubles getting an Optiplex 9020 into a very old case
Hi all, I'm trying a rather silly 'sleeper build' where I'm trying to build a modernish PC into a 1980s PC case to be an HTPC for an old CRT TV.
For this purpose, I got an old Dell Optiplex 9020 PC. It was working fine, and I setup all the software before making the transfer.
Now it is not turning on, and the only feedback I get is 2 beeps a gap and 1 beep, which my initial lookup seems to indicate may be a busted mobo. This error is the same regardless of if I unplug the RAM and GPU.
I'm just confused as to what broke in this simple transfer. The only 'major' change is I had to get a bracket for the CPU fan, since it doesn't screw into the case.
The only other things that come to mind:
- There's some sensor that seems to check if the PC is open. Thing is, it booted just fine with the case open before...but even holding that button down, no change.
- The board doesn't really screw into the old case, at all. Obviously a completely different standard. I just scewed in one case screw. Would this have any effect on actual function? Is there somehow some kind of short happening? I haven't tried putting it back in the original case yet, since it would mean taking off the fan again.
I'd appreciate any insight before I go out and buy a new motherboard for it, especially if the result would end up the same.
