I agree with JBI and go the AMD route,70-80$ for a decent 880g mb ad a relatively cheap 960t phenom that just might unlock into a 6 core chip:) But then you a bit limited on upgradability cpu wise.Now that i went back to look at you original post it seems your in the business of building computers for people,Perhaps start building AMD rigs for your cheaper systems.They run plenty fast for probably 90% of your customers.
With HDs being the biggest bottleneck in computers for a long time now and SSDs coming down so much in price.Call up some of your old customers and offer adding a SSD to there computers.Humm now that i think about it if a SSD can make a crappy computer snappy and quick it might make you loose a lot of sales of new systems.But SSD upgrades might make you additional income,You know your customer base better then any of us.
As for the monitors i just cringe even thinking about a tiny 20 inch panel.Sorry to say 4/3 panels are going extinct,16/9 took over like a virus with the invention of the hdtv,1st just a few then BAM ,they are everywhere.I do not mind them but a lot of professionals do not like them.Good luck to ya finding the monitors you need.109$ 21.5 1080p acer for 109$ at newegg http://www.newegg.com/Product/Product.a ... 24-009-306
also 20" 1600/900 for 99$ http://www.newegg.com/Product/Product.a ... 6824009317
you can find a few 21.5" 1080p monitors for 129$ acer,etc.
I also looked at dell thinking they might have some cheap small monitors but they are a ripoff
Microcenter sells the 2500k for 179$ and i think 50% off a motherboard on top.Thats one hell of a deal.In store pickup only.Opps your in alaska:( no microcenter on the top of the world.I do envy you though,would love to live there.So beautiful but also Wild.
