I'm looking at upgrading my system, but found that it would be better to upgrade everything to the new standard. Well what I consider the new standard (pci express, sata, etc). I just wanted some opinions, and thoughts to make sure that the parts I have picked will work with no conflicts but most importantly if the motherboard and video card will fit in my case (Lian-Li PC-60). I would prefer not to buy a new case, but I know that newer parts are bigger and this could force me to get a new case. Here is a list of the parts I am planning on: ABIT AT8 Socket 939 ATI Radeon XPRESS 200 CrossFire HIS Hightech Radeon X800GTO Antec NeoHE 500 ATX12V 500W Power Supply (definately want one with dual 12v rails and active pfc) KINGWIN KF-812-BK SATA Mobile Rack AMD Athlon 64 X2 3800+ 2GB OCZ Titanium (2) Western Digital Caviar SE16 WD3200KS Plextor IDE DVD Burner Model PX-740A/SW-BL I'm only upgrading to the "new standard", but with the room to upgrade, like adding another video card. Please feel free to recommend other parts, especially heatsinks. Thanks.
