thx, so i should go with either a x2 or x3 athlon in a gigabyte microatx am3 board (ddr2 is becoming rather expensive). Well then i should go with two low size hard drives in raid, maybe like 2 500gb wd's which should cost only 100$. I have no clue about high end pro sound cards but for consumer level i think the xonar will work, its probably overkill if anything but i think my bud might need the powered headphone amp. Thanks alot for the raid idea, didnt think of that. For OS i was hoping at getting virtual dj to work in wine but it doesn't. My mates bar already has a dj system its just outdated, proned to issues but i need to get a look at it. If its using a consumer level card and the jacks are all the same will then the xonar should work fine, also will see the os. I'd rather not have to buy the os for the system to keep the cost a bit lower, if the old system has xp that should do fine, like i said this system will be 90% of the time in the bar so its only purpose will be VDJ. To let you know though i have windows 7 pro and ultimate and they both run the VDJ trial easily. Im hoping to make the system portable so that my mate can bring it to his home and put his songs on it this way saving him setup at the actual bar.
