The key issue I've run into is whether or not the BIOS will support what
you want to drop in. Since your system already has a Harpertown (54xx)
CPU, I would guess it'll be fine. By contrast I cannot put L5420s in my
Dell PWS690 or HP DL140 G3 - even though the chipsets support them -
because neither manufacturer released a BIOS with Harpertown support
(that I could find, at least). The HP will identify the L5420 correctly
during POST, then the BIOS just won't run let alone boot.
