|A search (Google) for the p4vm490 MB leads to Tai used component shops. This cannot be a reasonably current MB. You can boot without a hard drive, at least as far as post and set up, but I am pretty sure you will not get anywhere near that far without RAM installed, so your conclusion is not valid. If you do not have compatible memory laying around, you probably should not waste any money on it, but with more information though, I could not tell for sure (what CPU type does it take for example?).|
You have to be a little bit crazy to keep you from going insane.
