I have been extremely happy for over 2 years with my 450 Cube, and will ONLY replace it one day for a 1gig (or higher) Titanium Powerbook with an external ADC connection. From the moment I purchased it I put in 1Gig RAM and an 80GB IBM Deskdtar 7200 drive (oh, and a 22" Cinema screen, which is truly wonderful). Earlier this year I upgraded to a GeForce3 64MB video card, which added fan noise, but improved scrolling and redraw speeds dramatically (since I still run only 9.2.2, any extra video ram would be of no use). I am watching the Powerlogix upgrade cards for the 2nd generation (so the first generation experiences a price drop). If I install the 1gig upgrade, which has its own fan, do I need to keep the fan on the video card running as well, or can I disconnect it? I have NEVER had heat problems with the unit (and miss the VERY quiet old but slower video card), and only keep some little 1/4" rubber feet on each corner to raise it up a bit and allow for a bit more venting.
