They've been consistently well engineered, and well built, have very good aftermarket support (BIOS upgrades and drivers are still available for nearly every board they've ever made, and they are MUCH better documented than the typical taiwan stuff). Intel has had a few funky chipsets that NO motherboards could fix (anything that used RDRAM, and worse, the chipsets that used RD->SDRAM bridges like the i810), but otherwise I've found them very compatible. I do try and avoid the chipsets with onboard graphics. I've never seen ANY documentation like ftp://download.intel.com/design/motherbd/lt/D5601702US.pdf (for the DP965LT, a current mainstream performance board I'd strongly consider using for a Core 2 Duo desktop) from any taiwan board maker. Note they actually give power specifications for the board, thermal design guidelines, etc. Detailed errata in ftp://download.intel.com/design/motherbd/lt/D6333603US.pdf (ever seen errata on a taiwan board? muahaahahahaha, right!) RHEL/CentOS 4 is getting a bit long in the tooth, and support for the latest hardware is somewhat lagging, this can be an issue with any new system.
