I have a Dell E521 that is in its original state except for a PSU i upgraded. It came with an Athlon 64 3200+ AM2 socket processor which works fine, but i am trying to upgrade it for gaming purposes.
I purchased a new Athlon 64 x2 6000+ AM2 socket processor because my system specs indicated my mobo would take any Athlon 64 x2. When trying to install it, the CPU chip would socket-in fine, but the heatsink/fan unit that comes with it will not rest flush on top of the processor chip because there are a few small components on the motherboard that are huddled too close to the socket preventing me from centering the heatsink on the CPU. I say again, the CPU chip would socket in fine, I could power up the computer that way, but the heatsink that came with it would not fit on top.
Can i use the narrower heatsink (no fan) that came with the original CPU and put it on the new x2 6000+, or do i need a whole new motherboard? I have no idea what mobo i would need, or would fit.

I purchased a new Athlon 64 x2 6000+ AM2 socket processor because my system specs indicated my mobo would take any Athlon 64 x2.
The system specs indicate the mobo supports Athlon 64 X2, which is not the same as "all" or "any" Athlon 64 X2.
E521 was introduced in late 2006, as can be inferred from your BIOS date (11/08/2006). AMD introduced several new Athlon 64 X2 models (and steppings) through June 2008. Generally, OEM boards are not designed with any particular consideration for future CPU releases in mind, but are designed to support the particular CPU models the OEM has planned to market or offer with systems that will be using the motherboard.
Athlon 64 X2 6000+ was released in models with 89W and 125W TDP. Do you know if your 6000+ model is 89W or 125W? The 89W model should be fine, but you might need the latest BIOS from Dell.
However, the 125W TDP model may not be a wise choice. OEM boards almost never support processor TDP in excess of 95W, particularly so for Micro ATX (or Micro BTX) motherboards. Even many retail Micro ATX boards are limited to ~95W TDP.
As for the heatsink, this board used non-standard attachment hardware, which requires some modification to accept standard third-party heatsinks. The Dell heatsinks I've seen for this model looked quite beefy, though. I would just use the Dell cooler with fresh thermal paste. If you don't have thermal paste separately, you could just scrape it off the AMD heatsink and spread it uniformly over the CPU.
