You also might want to check out Monarch Computers at http://www.monarchcomputer.com/
They have a nice budget system here: http://www.monarchcomputer.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=M&Produ ct_Code=90218
I would recommend upgrading the RAM 512, adding an OS (unless you have one you want to use at home), and extending the warranty to 3 years (only $50 more).
You might also want to check out Systemax. I think that's spelled right. If I were you I wouldn't blow $1,500 on a computer, it just isn't worth it. If you have any interest in building your own (the best option) check out www.amdmb.com, great resource. You might even find someone near you on there who would be glad to build one for you (for a small fee) .
