If the enclosure's half decent, that's actually a pretty good price for a nicer eGPU housing (aesthetics aside).
As long as there's no shitty trick introduced that would keep it from working with any PC with a thunderbolt port.
What is the difference between PCI Express Gen3X4 lanes and Intel Thunderbolt 3 Plug and Play?
The Alienware Graphics Amplifier’s technology uses a direct hardware connection, while the Thunderbolt 3 technology is based on a platform with shared bandwidth. Alienware’s amplifier will never share, or compromise, the bandwidth to your system’s GPU. Instead, it provides reserved high bandwidth directly to your system’s GPU with one unique cable connection. Alienware Graphics Amplifier utilizes four lanes of dedicated PCIe Gen 3. The Thunderbolt 3 specification is capable of either two or four lanes of PCIe depending on the OEM’s implementation of Intel’s technology. Alienware gains an advantage by having these lanes dedicated to graphics that are not shared by LAN, USB or display ports.

Not active yet, but the sale price tomorrow is $77.99 vice (pun intended... ) the regular price of $129.99. I waited quite a while for these to come up on sale, but ended up buying it at full price after not seeing any sales come up.
Pretty happy with it, and I believe 3.0Charlie also sings it's praises.
