Hi, do you guys know if A1398 2015 MBR SSD is compatible to the A1419 iMac 27" late 2013 ?

Hi, is there a way to trick the iMac to "think" it is connected with the LCD? I am thinking to use the hardware without the display panel. However, my iMac is very slow and the fan is at this full speed when the display panel is not there. Thank you !

Has anyone tried to used the iMac without the display panel ? Mine runs at full fan speed and the startup screen turns into purple colour !

Can anyone tell me what is happening?

Has anyone tried to connect a external wifi antenna? The wifi antenna connector is broken by the previous user. I am looking for 2 wifi antenna. What I want to do is to attach the wifi antenna outside the MacBook air to improve the reception.

Does any one know where to buy the antenna (only antenna, not with isight camera.....etc) ? Is Ipad antenna compatible or any other apple product?
