I can deal with and understand that there may/will be spacing issues with the oversized tower heatsinks, but my questions is really about the mounting. Are the hole spacing the same? Is the mounting method the same? Are the hole sizes the same? If 1366 server boards as a whole do not use the same sizing, spacing, and method as a regular 1366 consumer board, then I wouldn't be able to use any aftermarket (or even OEM Intel) heatsink, regardless of the actual size of the heatsink itself.
