I put together a dell Optiplex GX520 from parts obtained from dell and ebay. I have everything needed but didn't realize it didnt have a heatsink and fan shroud. I had to order it and it will take a few days. It does have a big fan in it. I have a Celeron D 3.33GHz Processor in it. Can I turn it on long enough to check out the bios without damaging anything until I get the heat sink? I just want to make sure it starts up at this point. I'll turn it off as soon I see something. Let me know if I will do damage. Thanks!
