Is a used Dell Poweredge 1900 Tower a good used Server?

Thanks for your answer.I'm just planning to use it for a Home Server(running Linux)for now,on a few hours a day(in my computer room upstairs):File Server,LAMP Server(just local),media server and other uses.

This of course depends on what you are going to use it for.  While its hardware is far from cutting edge any more, it is also far from obsolete, so it depends on if the price is right and if its hardware is capable of what you want to do with it.

Keep in mind with that model on eBay that the RAID controller is not a Dell-supported controller (it is third-party) and seems to have no write-cache (at least not that is mentioned in the specs), and it only has a single processor (but supports two).  As far as the noise goes ... while they can be noisy (depending on environment, hardware configuration (16GB RAM, PERC, PCI, etc.), some report having replaced the fans (with some trial and error) with quieter models, however, nobody should buy a server with the expectation that they are quiet-running machines, so consider where the server will be placed before purchasing.

The 'raid controller' that is listed (39320) is actually just a SCSI controller. The 1900 only ever shipped with SAS drives. It doesn't seem to have a raid controller, so the drive(s) are probably connected to the onboard SAS controller. If you don't need (hardware) raid, this server should be pretty decent.

As it currently has a 5335, it should be a "II" model. If you ever opt to upgrade or replace the CPU, you want to avoid the 5200 and 5400 series Xeons as the 1900 never got a motherboard update to support those Xeons and is limited to the 5000, 5100 and 5300 Xeon ranges (and not all CPUs in those ranges may be supported).

Ha ha ... good catch the 39320 is SCSI ... totally overlooked that (how embarrassing :)), although the Adaptec page says RAID 0,1,10 for it.
