The MX-1 is a good enclosure except that its fan is not quiet. I use one for backups, but would not be willing to listen to it for long periods of time.

A hard disk is not an archival storage medium. If you write it, then put it away and hope for the best you may get a very bad surprise. But as inti points out, you can use hard drives with multiple copies to get reliable long-term storage, and inti points out several good tips on how to do this. But...

Before buying a 3650 please check recent video card articles at anandtech.com --- I vaguely recall (perhaps in a review of the 4650?) that there was some problem with HDMI in the 3xxx series, but that it works properly in the 4xxx series.

>If that's true then how to explain that his folding is using 2 processors at 50%??

50%+50%=100%. The uniprocessor client has enough work to keep one core fully busy, but it doesn't stay on one core, it gets preempted by other processes and when it is resecheduled it is random which core it runs on.

It could be the firewall at work. I had a problem about a year ago where (if I remember) all the linux SMP work units were distributed by a server on port 8080, none via servers on port 80, and the firewalls at work were set to block access to port 8080.

What you describe is likely your case resonating with the disk vibration -- which is particularly pronounced with multi-drive systems.

Hi, Autoboy. I think you can't get the big points with the single-core athlons. The main reason for the high PPD of the successful dual- and quad-core folders is that the SMP jobs (especially the 64-bit Linux SMP jobs) have much higher PPD values than the uniprocessor jobs --- in part because the SM...

My rule of thumb is 10 watts per stick of DRAM, and 10 watts per disk drive.
I would buy the DRAM for performance reasons. Surely you can save 10 watts somewhere else in your house or apartment with little effort if you are looking to be green.
