Yep. Drive bays are standard, power supplys are standard. You pick the case you like (about a gazillion choices), add fans (standard sizes here too), and you're off to the races.

The industry standard is the AT box. There are smaller boxes that use the ATX standard which is usually a smaller system board and power supply.

Actually ATX is the current standard. It's not all that easy to find AT compatible cases anymore and certainly not AT motherboards. There are a staggering aray of cabinet options. Many cabinets accommodate mini-ATX much better. You need to asess your needs for extra optical media drives, floppy drives (a lot of newer motherboards don't directly support them), ATA, SATA, or SCSI harddrives and how many etc. and get the case and motherboard that accommodates what you need now and what you think you're likely to want later. For most users 5-7 PCI expansion slots are just exess bagage. A lot of the motherboards availble for ''home-builders'' have only 2-3 of them. The cabinets vary similarly also. It's sort of a balancing game based on how and where you plan to use the PC.
