Can I use a new 27" imac as a display for a PC with DVI output

Hi,

My PC is kind of old, but I need to have it for work related things. Unfortunately is doesn't have a display port out only DVI and VGA.

I want to buy a new iMac (27") for personal work but I don't have room for multiple monitors in my current office setup.

Is there any adapters or any way to use a 27" iMac as a display for a DVI output PC?

I keep getting contradicting opinions when searching

I wrote the other day about VMware (which will have to be my option if I can't get the iMac to work as a monitor, but I have a lot of data stored on my PC so I'd rather keep it and just have one beautiful 27" monitor

Thanks for any help.
