Recently bought a refurbished HP pavilion slimline s5000 series. It came with Windows 7 and it sets up when first started. I have two computers with Linux Mint Debian Edition but this computer is for my spouse and I wanted to put Linux Mint 12 LXDE on it thinking it would be a bit smoother and require less updating and etc. I made a usb stick with LXDE for the install. It did not go well.
Grub did not install and I was unable to install it or to update it. Tried to fix that by re-installing LXDE and that did not work either. It created another partition and conducted a complete install on that new partition. I then had two installations of LXDE and one of Windows 7 on the same hard drive. I finally decided to just stick with Linux Mint Debian and made a new cd for that. And that worked like a charm.
I sort of feel like LXDE needs a bit more testing and work.
