HP Pavilion Slimline s5710f: AMD Athlon II 260 Dual Core 3.20GHz, 3GB DDR3, 640GB HDD, DVD Burner, Win 7 Prem $300 + Free Shipping

Staples [staples.com] has the Acer P216HV bd 21.5" Widescreen 1080p LCD Monitor for $99.99 + free shipping.
Although $25 off $75/$100 coupons don't work online anymore FOR MONITORS, you can order BY PHONE, or print one out and buy it in-store, making this monitor $74.99 AC. YMMV
-- I tried to use the $25 off $100 I had on the dell 20" online and it didn't work. Then called them and gave the rep the code, ordered in less than 10 minutes~
