Ok heres my deal. I have 2 Optiplex 745's that I want to put nice dual slot video cards into. I run into the problem opf the Video card hitting the ABNORMALLY large heatsink assembly in the 745. What I need to know is, before I go ripping this thing apart, will a normal 3rd party heatsink/fan combo fit in this machine? If thats the case I can go buy one and take out the existing one and be able to put my cards in these machines.

What video cards are you thinking about using? The Dell are very limited (if possible at all) when it comes to upgrading to dual cards.

You can find the specs here.

What model 745 do you have?

I meant the dual slot card(Cooling fan vent covers second slot). not dual cards in each one Sorry for the confusion. I am going to use a Radeon HD3800.

The Optiplex GX745 Core 2 Duo Midtower.

my first obstacle is replacing that giant Heatsink etc with a standard one so the extended length card can fit in the slot

The power supply isn't big enough to drive the 3800's.The HD3800 needs about between 450>550w power supply depending on model. The Dell you have only has a 310w PSU

You'd need to buy a bigger aftermarket power supply before doing anything else. Sorry...

Any other insight on whether or not I can put a smaller heatsink/fan on this pc without much of a problem?

Did you manage to do this.

I dud just this last night, I hacked the Case, and "Modded" :o the Heatsink and Shroud to make the 9800GTX+ fit. Its nice and snug now, but I wonder if there is a better Solution for Disipating the Heat now that I have "Re-Arranged" the Shroud.
