whoa whoa whoa...every needs to calm down.
From working in the computer industry, hand-in-hand with some of the largest companies in the US & around the world, I can tell you that for Windows based machines, DELL are used by about 85% of the customers.
DELL builds some of the best server grade machines out there right now. When you buy
any off the shelf model, it's tailored to someone who wants all that software and garbage (its called features). Your computer is 3 years old, that's a pretty good run if you ask me, considering hard drives do have an expected life.
Also, I will agree that the hard drives in DELL machines are garbage, but they're also the same generic hard drives found in most computers out there (again, trust me, I do this stuff all day).
Your best bet, build it yourself, or have one built for you. However, like I said, a server grade DELL machine will not dissapoint.
p.s. You should always reload any machine you buy!!!! There'll be backup disks for any software that's pre-loaded which you may want or need.
p.s.s. Dell has moved all of its customer support back to the US.
