i either build one (best way)
or for the business i just go to costco and pick one up
costco usally only has decent working comps and there return policy is so good
brands don't matter much they all use the same internal components
HP, Dell, Gateway all make bad computers ok computers and good computers just depends on whats in it
as far as bloat i always wipe any new comp i get and do a fresh install of the OS so i know i have a clean system
