Motherboard Replace

if i understand you correctly, the motherboard mounts fine, it also fits the back connector plate fine. your problem is the front panel I/O as in the power, reset, pwr led, hdd led, headphone jack, mic jack and/or usb ports.
well if thats your problem then no it wont fit and there is no adapter.

but you can disassemble it and plug them in directly though. if its the right type of connector, then you need to put heat shrink tubing on it to prevent the wires/connectors from touching each other. or if your lucky and you have the plastic plugs from an old standard (non-proprietary) case, then you could just move the wires into that.

otherwise you need a new case. you can get some super cheap just check reviews before you buy one.

and if your actually expecting an email and never check back here then.... too bad.
