I test a lot of iPhone cases and rarely get comments. Most of them aren’t that distinctive. But a new iMac-inspired case from Spigen attracted the attention of my teenage kids and even elicited a compliment: “Cool case, Dad!”

iPhone case-maker Spigen is launching a set of iPhone X cases inspired by the original see-through iMac G3 and the first-generation iPhone.

With a see-through outer shell, Spigen’s Classic C1 resembles the original iMac. The case commemorates the 20th anniversary of the machine, which Apple launched in 1998. The iMac was the first of a string of hit products following Steve Jobs’ return that turned Apple around.

Just like the original iMac, the Classic C1 comes in a range of colors: Bondi Blue, Ruby, Sage, Graphite and Snow. Two more “surprise” colors will be announced later, Spigen said.

Make your new iPhone X look like the first iPhone

Meanwhile, the Classic One case makes your iPhone X look like the first-generation iPhone. Featuring an aluminum-colored back with a black bottom plate, it makes Apple’s latest handset look just like the first one. How’s that for retro cool?

All the cases are a dual-layer design. A hard plastic exterior protects against scratches and scrapes, while a rubbery interior protects against drops.

I’ve been using one for a week or more. It’s rugged and well-made. The case fits snugly and, while it adds a bit of bulk, the phone still slides easily into and out of my back pocket. My phone took a tumble, and there’s nary a mark.

The iMac-inspired case looks good. My kids snatched it up at dinner over the weekend and passed it around. They liked the see-through back that shows mock internal components.

The cases are available on Indiegogo through a campaign that runs for 30 days, starting Monday.

The Classic C1 costs $25 for a limited time during the campaign, but a super-early bird special reduces the case to $18.

The cases are also be available in a pack. A Multicolor Classic C1 iPhone X Pack is $80 for the five original iMac G3 colors.

Spigen is also offering bundles of the Classic One case and its F306W wireless fast charger for an early bird price of $70.
