Nice comparison. Shows how much of a deal the T6212 is.
Just for fun I went and built a system at Cyberpower.com which would match the stats of my eMachines T6212.
X-Dreamer Case 350W w/ Window (BEIGE)
(939-pin) AMD? ATHLON?64 3200+ CPU w/ Hyper Transport Technology
(Sckt939)MSI K8N NEO4-F NF4 Chipset Mainboard
512MB (256MBx2) PC3200 DDR400 Dual Channel (Major_Brand)
160GB 7200 RPM ATA 100 HARD DRIVE -- Recommended
NONE - 2nd Hard Drive
None, or On-Board ATI Radeon Xpress 200 16X PCI-Express Shared 128MB Integrated 3D Graphics Video Card
NONE - Video Card
56X CD-ROM (BEIGE)
16X DVDRW/CDRW DRIVE (BEIGE)
NONE - MONITOR
HIGH DEFINITION ON-BOARD 7.1 AUDIO
6-1 media reader
Now, the onboard audio is 7.1 vs. 5.1 for the eMachines, I'm sure the motherboard may be a little better model, and the cd-player is 56X vs. our 48x.
Price comes to $742 w/free shipping.
Price for T6212 w/rebate (not including tax) is $579.
