Description from their page:
TUXEDO Computers are customizable Linux notebooks and Desktop PCs optimized in the first place to run with Ubuntu-based Linux operating systems. Literally Linux hardware in a tailor-made suit.
I’ve been wanting to buy a laptop from them for awhile, but I like to assemble my own PCs and honestly don’t need a laptop. At this point I’m just looking for an excuse to support such companies…
I guess their desktop market is towards businesses? No idea. Personally I’m also more interested in their laptops and indeed love building my own desktop as well.
