I'd like a P4-ready, fairly compact system with good access and cooling. The last 3 boxes I built were calculational nodes; modest AGP graphics cards, 1 GB rdram or DDR, one 7200 rpm hard drive, a simple CD-rom and floppy, and 0 to 1 PCI card. I have 4 mid tower cases around my desk, and it seems like overkill, and a waste of space. If the system has onboard ethernet, I need 0 pci slots.
I'd like something with a power supply adequate for a Northwood P4 and modest video card, easy access to the guts, good cooling, and enough bays for the CD, floppy, and 1 hard drive. I'd like a case that could be opened up quickly, with no futzing to get to the drives and internals.
Then again, I'd like to be 20 years younger.
