Yes, the DG45ID has a "Consumer IR" header block. AIUI, this header is based on a Microsoft standard to allow system integrators to include IR capabilities in custom builds for XP/VIsta Media Center Edition.
Unfortunately, there don't seem to be any companies (currently) selling IR receiver modules that are compatible with this header. And the few HTPC cases I've seen which include IR receiver modules all seem to use USB headers, not CIR.
One alternative that I've seen discussed several places on the web is to buy an regular Windows MCE remote kit, disassemble the dongle, and mount the IR receiver in 3.5" drive bay. This still means connecting through USB, not CIR.
