Rip out its HDD and then use the system for its screen, can I do that? I don't know if I can just plug in the cable and be ready, because I have a cable for it and yeah.. how would I do that without the OS? It has no video card, so?
It has an HDMI (input only) so you should be able to hook anything you want up to it. I don't know if the touchscreen functionality is maintained on the second PC. I doubt it.
You can buy a 23 inch touchscreen for $350, which would be cheaper than buying the all in one.
I wouldn't rip the hard drive out of it. It makes no sense.
There may not be any functionality as a screen unless you have the proc and hdd in the box. Meaning, the device may not turn on at all without the internal system working. Does it have a function where you can switch the input from the PC that is integrated to the HDMI? Does it even turn on when there isn't a processor installed?
I'd remove the hdd, or better the processor, and see if you can still plug a DVD player into the screen and get sound and video to run on it. It depends on how the manufacturer set up the box. If a DVD/Blu-ray player can be hooked up to it via HDMI when no HDD/proc is present then a PC with a DVI/HDMI output will work too.
No no no... I see exactly what you want to do and this is not the right way to do it. Just buy a touch screen monitor, not an all in one computer... You will need VGA/DVI/HDMI to carry the picture and USB to carry the touch input.
Omg nobody sees what I want to do, I already that the touchscreen PC, I`m buying a new rig minus the HDD+i3, and screen, all of which I have on this pc, see what I mean now? I`ll be connection a PC to this, except its gonna be empty on the inside, I`m wondering if it will still work.
Seriously... I'd just spend $120 on a 22 inch 1080P monitor and leave the other system intact. If you wanted to borrow the PROC/HDD from the all-in-one fine. You could replace the i3 with a cheap $40 celeron processor and a $40 60 Gb SSD in it and it would run fine.
