Sure... headset and seatpost might be different. Neither of which are big dollar items if you need to buy new ones. Personaly, I just bought a cheap lower rent RaceFace seatpost from JensonUSA when I built my Titus, figuring I would upgrade later. It's 50g heavier than my lightweight blingy post, but honestly I don't notice.
Some carbon frames have regular headsets, some zerostack headsets, some IS, some tapered variants of all of the above. You just have to get whatever your frame needs to make a regular 1 1/8" straight threadless fork work. Should be no big deal.
The most important part... you'll have to measure your fork steerer tube to make sure it's long enough. Specialized steerer tubes tend to be on the short side, but it looks like the steerer tube of the carbon frame is pretty short too... plus, it looks like you have a few spacers in there you can remove if needed.
If the steerer tube is too short, then you are into some bigger $$$ for a new fork... or at least new uppers for your existing fork.
Also budget for some new shifter and or brake cables. Shouldn't be too expensive. I'll bet your BB will just move over, too.
*edit*
Oh, that's a 29er Hardrock, right? Hard to tell in the pic.

your reba fork won´t work, the chinese frame has tapered headtube. the rest seems to fit. I´d personally do the switch since is not complicated at all, IMO. Just start swapping somethig, then you won´t stop till you have the complete bike assambled.

Thanks guys. Great info!
Im gonna see if I can find a similiar frame that accepts my fork cause I def dont wanna have to buy another one...
Has anyone seen a chinese carbon 29er that uses non-tapered tube?

You just use a 1-1/8 reducer for the bottom headset cup. then you can use a straight 1-1/8 steerer.

For sure you'll need:
-seatpost - Specialized uses 30.9mm posts, that carbon frame uses a 31.6mm
-headset - You'll need a tapered reducer headset to use your existing fork.
You might need:
- seatpost clamp - your current one may work. You'll need a 34.9mm.
- longer cables and housing for both shifters and brakes
- front derailleur - the clamp size is the same but it looks like the Spec. has a bottom swing and the new frame might need top swing.
- different length stem - Your current one will work but might not be the optimal length for the new frame.
Everything else should work on the new frame.

You can use a straight tube Reba in a tapered head tube frame. You just need a 1.5" to 1 1/8" lower headset. Cane Creek makes one... or install a reducer.

I have a Hong-Fu carbon frame, which i believe is the same as the frame you are looking at, but it comes in odd number sizes (17", 19" etc).
Things I would look out for:
Rear tire clearance: Maximum of 2.1 on my frame.
Rear brake rotor clearance: Maximum of 160mm.
Other than that everything should transfer over nicely. You may want to check the length of your steerer tube on the Reba to make sure its long enough.
