I'm weird, but my dream computer is a fully kitted out Sun Ultra 45. Dual UltraSPARC IIIi 1.6 Ghz processors, 16 GB ECC RAM maximum, XVR-2500 GPU (or perhaps there's a faster supported card?), and as the pièce de résistance, the SunPCi IIIPro - an entire 1.6 Ghz AMD Athlon x86 PC on a PCI-x card so you could run x86 Windows and Linux inside SPARC Solaris.
That's my dream computer. That's my white whale.
@thomholwerda I've always wanted to have a pre-Nehalem Mac Pro and two 30" Cinema Displays. And I have it now. I've had it since it was still relatively current, by modern standards it's showing its age already, but I still like this machine. Mine's not maxed out, it has top CPU for this model, but I think I can put 4 more gigs of RAM into it — 28 is enough for the though. I have GTX680 with Mac-compatible firmware in it — also pretty old card now, but not too old.
@thomholwerda Using anything non-x86 and non-ARM might be problematic today, I have PowerMac G5 too— a lot of software requires patching, some outright incompatible, for example Go is poorly supported on PowerPC and I can't build some of my favourite software. You could probably solve this problem with that expansion card.
Having your dream computer makes you lose interest in getting new hardware I think.
@thomholwerda No, I, of course won't be against having a Talos ][ workstation, but I'm not sure I ever have spare funds for that 😅
@m0xee I have two Talos workstations in my office, but they're not mine - on loan from the company that makes them!
