Thanks everyone.
CPU, doesn't matter much, personal lab so anything that is available today will be suffiecient. GPU, no difference either. I will have a mixture of win & linux, no care in the world for anything special on graphics -- basic is good.
Budget, that is a little flexible but if I can stock it with 4 GB now and then incriment I'm good with that. 16 would fit the bill great, don't need too much more. If there was a board that support low/mid 20's, that could be possible but likely tops. 12 would probably suffice. If I can setup a base MB, some ram and no thrills beyond that for $500-700 then great.
It is for my home to lab out system configs. Mixing Win AD and linux with various setups. I"m a systems admin but lacking in much of the specifics on the availability of hardware that is out there. Desktop style unit that supports a decent amount of ram is basically what I'm looking for. I'm a little out of touch with where we are hardware wise in this area for my needs. I don't want to get a RAM style that is about to be obsoleted (upgrading the RAM every few months or so) or to get a MB that has RAM type that is the most expensive. And also, help with not getting the crappy board that will die in 6 months...
Hope that helps ...
