Ask Slashdot:Linux-Friendly Components Vendors?

bleachboy writes "We all know about VA Research and their fine complete system solutions for Linux, but I am the type of nerd who likes to put my computer together piece-by-piece. Can anyone recommend a hardware vendor (i.e. mobos, memory, cpu's, etc) who is known to be Linux-friendly? Not that it matters particularly when buying piecemeal hardware, but I like to support companies worthy of support! :) "
