How is Dell XPS 2020 Desktop Quality? Is it worth the buy?

I have been an HP user, However the HP Pavilion I purchased lately ended up having a Fan issue, I returned it and now i am looking at DELL XPS Desktop PCs.

I have been using my old HP for 6 Years without any issues. Only Upgraded the power supply.

Is it Possible to rely on DELL products? specially desktops?
