Well, how about this Anaconda.
My sister and my dad have the 6805. Both have the same problems. Both were from different stores, different shipments. People have been complaining about the same problems on this forum for over a year now. The sticky thread about flicker is huge.
That says these machines are trouble.
Hell they shipped with a HORRIBLY broken BIOS that was incompatible with SP2! I have a P2-233 notebook running XP SP2 right now, and that machine is from 1999! And a Pentium III machine at home. And a Pentium PRO! Even a K6-3+ on a known-to-be-trouble MVP3-based board!

My sister accidentally installed SP2 and she had to wipe her machine and use the restore disks to get it working right again. I told her never to install SP2 and to disable auto updates. She's a grad student and doesn't have time for bullshit like this. Finally, eMachines brought out an official BIOS. I had been using ripped BIOSes from the newer machines for months but I didn't want to potentially void my sis's warranty. Why didn't eMachines get that BIOS out months sooner?
They also can hardly be upgraded reliably with respect to RAM. I had troubles with stability with two different RAM sticks. After hours of troubleshooting, I discovered that the internal slot is slightly more stable. I stuck my 1gig stick in there and left the "user serviceable" slot empty. Not the first time we've heard about this issue either. Read back a bit about people finding out which sticks don't work at all with 680x. I intentionally bought a Samsung stick to be sure they were the same make too.
The Cardbus controller is cheap trash that has issues with Audigy PCMCIA. The bad ACPI support in the troubled BIOS compounds this with stutters and static. Works perfectly in my Dell 9300.
Both my sister and I had our power bricks burn out within the same month of age!

Oh and 2 of the 3 machines I've seen have bad pixels. I had Best Buy crack open and let me check them for bad pixels. The first one I bought I didn't check with a black screen, just white. Oops. Second one I bought a few months later and I checked both white and black, found a dead pixel. Best Buy grabbed another from inventory for me and that one was OK. You must verify before you leave the store though or you're stuck with it unless it's just loaded with dead pixels.
Nice screen (if it's not flickering) and optical drive (quiet, fast, reliable) though! Realtek audio is decent for AC97 too.
My new Dell 9300 (sold 6805 to dad cuz I couldn't sell it on eBay with its probs, need to be on call on site lol) has been absolutely trouble free. I've been using it 7+ hours a day for 6 months now (I use it as my primary machine at work). It is an awesome machine. I've also been following the Dell Tech forum in addition to this one. People on the Dell forum are not having huge problems that are all the same. And you ain't seen support until you've seen what Dell's website can do for you! Dissassembly guide? Check. Drivers easily available? Check. Driver UPDATES? Check. Knowledge base? Check. Official Forum? CHECK! Easy to obtain replacement parts? CHECK!
eMachines' site is utter useless trash.
I bought the 6805 in Spring '04. I used it for a year. I pushed it hard with lots of games. I liked the machine even with its problems, but only because I consider myself an extremely advanced user that can do things like tweak PCI registers to get the crappy cardbus working better, and know that SP2 wasn't the problem, the BIOS was. And to know that the RAM I put in wasn't defective, it was the slot. And that I knew about this forum for common support among users. I regret voiding the warranty somewhat, considering the number of problems, and the potential for a bad mobo/usb. But from what I've read eMachines/Arima/Gateway support sucks ass at actually solving the problems anyway.
I don't see why you back up the 68xx series. They are trouble.
