Same here, only bad thing I can say about Dell is that they had a string of bad lite-on optical drives. And they issued a recall and called the users personally who were known to have the machines.
Dell is a great company for machines on the desktop. I even helped my mother buy one, and I build machines (roughly 1 or 2 machines a month).
Oh, and at the end of this month, my RAID 5 array will be finished. This will bring my apartment up to 1372GB (1.3TB and yes, I did that using the 1024 method) of HD space. I'm moving my 470GB FTP to a 600GB effective (720GB actual) Raid 5 array, and then using 2 external 250GB drives for detachable storage on my main machine.
Sorry, had to brag.
