What is the Best Computer You Have Ever Used?

I waited too long to order my dream machine. These were the best computers I've ever had the pleasure to test drive. I've been hoping to see Psystar computers on ebay, but no such luck. I'd like to build my dream machine, but we're not allowed to ask such questions in here (LockerGnome) >=0/

| Psystar Corporation is a Miami, Florida based company which sold "Open Computers". These computers, first announced in April 2008, had the option to be pre-installed with Mac OS X Leopard, making them the first commercially distributed non-Apple Macintosh computers.[1] In November 2009, a U.S. Federal District Court ruled Psystar violated Apple's copyrights in doing so.[2]

Probably the Mac Pro sitting on my desk right now. I've had computers prior to this but none have performed this well.

The best one I ever used was a $3000 build that I did for someone.

core i7-980x for the CPU 12GB memory, Radeon HD 5970, 128GB WD SSD, 2TB 7200RPM drive

After overclocking, it ran second life extremely well (didn't install other games as I didn't want to muck up the OS with DRM like securom and other DRM's then manually removing them.

The best one I ever used was an iMac or Mac Pro at the Apple store.

The best computer I have ever used is the Mac Pro I use for editing at my university. I also love my G4 cube. =)

The computer I am currently on, a MacBook Pro (Mid 2009) 15inch 2.53ghz.

I would have to say my Mac Pro. It has enough resources so that I am not restricted by what my computer can do, but rather by the limitations of my imagination.
