Eddy, which brand of the Radeon 4870 did you use has your reference (Visiontek, Sapphire, ect..)? Do you know of any company that doesn't follow the reference design? I don't want to buy from a company and your block not fit on the card. What is the "8/10 & 8/11 Screw In" option?
Also, thank you very much for making this block! I can finally order the parts for my new PC. Thanks again!
