The Dell Optiplex small form factor PC has been the mainstay of many companies globally for a long time, I know a few that are still using them. I got hold of one after an IT upgrade and have been using it as a file server on my home network for about 5 years now. I have 3 external USB drives, 2 Network drives and used to have a pair of printers hooked up to allow file sharing and printing for number of laptops via wireless. The printers have gone and been replaced by a wireless printer (stops me running up and down to the attic) but the rest is still there. The computer is on 24/7 and also acts as a MP3 streamer over the network. I can have no complaints it works, through a homeplug network to my wireless router it is providing decent file transfer speeds and excellent reliability. The only real downsides are the small form factor so there is limited upgradability mainly for space reasons and on 1/2 height PCI cards can be used. Other than that as long as you realise it'll never be a top rank gaming machine it is a perfectly usable computer, will handle the Office suites well and as its getting on a bit Memory is dirt cheap. Oh yeah it can be a little noisy under high demand, this isn't a problem for me, and its not unduly loud, just loud enough to make itself heard when the house is quiet. But as with a lot of this type of PC its just about bullet proof and i think it'll keep going for a good few years yet.
