Well, mine arrived this afternoon, and it's spectacular! I haven't had much chance to use it since it got here, as I had to pop out to pick up my car from the garage. Specification: 3 Ghz Xeons, 2GB RAM, 160GB HD, ATI 1900 graphics card, BT, Airport and twin Superdrives.
I haven't really had much exposure to the Power Mac/Mac Pro lineage and I'm not normally one to get over-excited but this thing just looks extraordinary. It's a work of art. The first thing you notice is the sheer weight of the thing - seriously, it weighs a ton. I had to make sure I cleared a route from the kitchen (where I unpacked it) to my room (where it will be living). This is the first computer other than my Mac mini (which is cute) that will be going on top of my desk. It looks that good.
First impressions/observations:
The startup chime is far too loud. There's also an internal speaker, which said "English" to me as I started the configuration assistant thing. That will be getting turned off at some point.
Noise isn't too bad - it's noisier than my Mac mini and the hard drive it came with (a Seagate 7200.9) is quite noisy as well. There is a low hum coming from it, but it's not too bad. The supplied hard drive will be relegated to running Windows XP, when I get round to it.
Both Superdrives are Pioneer DVD-111Ds. Not tried them out yet.
Hard drives are *very* easy to install. I addd a pair of Seagate 7200.10s (250GB and 500GB) and it took about five minutes at most.
The memory risers take a fair bit of effort to yank out. The memory in my Mac Pro is Hynix.
Seems very snappy (unsurprisingly). Windows zip around the screen (1680x1050 resolution) as I drag them around.
Mac OS X 10.4.7 is installed, unsurprisingly. The build is 8K1124. Software Update hasn't prompted me for any updates other than one for iPods.
Boot ROM version is MP11.005C.B00. SMC version is 1.7f8.
Interestingly, System Profiler has a "SAS" category under "Hardware". Presumably the Mac Pro will support SAS (Serial SCSI).
I am downloading Cinebench, and I'll attempt to post some benchmarks in due course (not used it before). For some reason, it's downloading at 100K/s, even though the connection can go four times as fast.
