>>In general, if I need a bunch of machines all alike, I'd rather buy something like the eMachine or HP box and make minor additions - I stopped imagining that there was money in building custom boxes a while ago, and if the box came pre-configured, I'm not putting my butt on the line for warranty and baseline tech support. YMMV, but I like it when the box has color coded connectors and a big,friendly picture that the average 4 year old can use to put the machine together. If pops can't figure it out for himself, just drag one of the youngsters in from home...

>Back in the olden days, when we actually used to SELL H/W (we now only do in-house), we carried Eagle, Leading Edge (models D & M), KayPro, Everex, etc. When we'd order 3 or more from any of these, we'd ALWAYS get different units, no two were identical, even if they were supposed to be the same! We used to put a lot of AutoCAD systems in schools, but no more, thank gawd. At least all the Compaq's would show up the same (and have the same problems!), so one fix would fix all. And the Compaq's come with those same color coded connections and charts you mentioned. Say, know any 4 year olds available for Compaq H/W installations? < BG >

I've got a 5 year old niece and a friend with a precocious 3 year old. And they work cheap!
