After much pain and suffering I managed to upgrade a 2005 Dimension 3000 to a modern OS. Steps: 1. Maxed out RAM to 2gb 2. Upgraded XP to Vista 3. Upgraded Vista to Windows 7 This machine has no SLIC, no DVD drive and wouldn't install an OS from a USB stick (although it would try, but not complete). Why to do it? Too much time on my hands. I noticed it hiding in a corner collecting dust, so I had to act. It actually runs very nicely. Next project: I ordered a mSATA-IDE adapter and will upgrade the HD from an 80gig IDE to 128gig mSATA. Thanks to murphy78 for the AIO (via TPB).
