My favorite project enclosures are salvaged from serial and printer A/B switch boxes of yore like these:
I often find these at swapmeets and fleamarkets for as little as a dollar, or even free. The cases come apart with a couple screws, and .060" PCB material is a perfect replacement for the end panels. There are standoffs molded inside for mounting PCB's.
They're great for station accessories like the antenna switch/control indicator box I built:
Lower right is an example of a K1EL keyer I made in one of these boxes:
The two N5DRV keyers in the photo I bought at Hamcom last summer from a silent key estate. He liked the same boxes I do, and he also built one into an enclosure you used to be able to buy from Ten Tec. The upper left keyer with the palm mini paddle is a K1EL I built into a Pamona mini project box.
For the front panels I print the graphics on two 4x6" shipping labels. One label is used as a drill template and the second one gets applied after all the holes are drilled and panel de-burred. A self adhesive clear laminate is put over that for a glossy durable surface. Printing inverse (white on black) gives projects a silk screened appearance.
Hard to beat such a versatile and nice looking enclosure, especially for a dollar (or less).
