Basically, I plan to install Windows Server 2008 R2 x64 on a machine by plugging in the video card initially and then I plan to remove it completely because I need the slot for something else. The motherboard has no integrated graphics. Would I be able to RDP once I remove the video card even though the motherboard has no integrated graphics?
Solution:
As long as the system is turned on and connected to the network, configured properly, etc. then yes, you can. This is how server administrators access “headless” servers
One note though: many BIOSes refuse to boot without graphics. Check your BIOS first, or else you may be head-banging the keyboard. If you have a PC SPEAKER connected to the motherboard (not a speaker system), then it should sound 1 beep if all is well
