itsy bitsy pieces.....
So my computer sits next to me, in tiny little bits, a victim of my poor planning and Dell's thirst for bucking industry standards. :(
It should come as no surprise, but the retention guide they used for their 478 socket on the Dimension 8300 isn't standard, and as such the new fancy heatsink I bought won't attach to the board (yeah I went ahead and bought the Zalman 9500 mentioned below, $53 out the door at newegg).
Hopefully though, there is some hope. Somebody offered to ship me a standard retention guide they had extra (cause trying to find them online to buy is damn hard...trust me) so with any hope once it arrives I'll be able to work things out just fine. I have a backup idea, that would involve me fabricating a custom mount, but i'm hoping to avoid that if this works.
