It seems that like all magazines, you forget entirely about the 'REAL PCs' in other words, custom clones.
Standard parts are much easier to obtain as well.
Not to mention the quality issue. In short you can spend more for a proprietary 'Brand Name' machine with generic parts and poor construction, just for that brand name on the box. Or you can find a good local computer shop and have a top of the line custom machine built. You do your readers a big disservice by only reveiwing these Junk Box machines.
