The MINISFORUM Neptune HX77G is a small desktop computer with the guts of a gaming laptop. It measures 205 x 203 x 69mm (8.1″ x 8″ x 2.7″) and houses an AMD Ryzen 7 7735HS processor, AMD Radeon RX 6600M discrete graphics, and support for up to 64GB of RAM and two PCIe 4.0 NVMe SSD drives.
It’s also a cheaper alternative to the MINISFORUM Neptune HX99G, which launched earlier this year.
The two computers are nearly identical when it comes to physical design and ports. But the HX99G has a Ryzen 9 6900HX processor which is a slightly older, but all-around very similar chip.
Still, it’s likely cheaper for MINISFORUM to source a current-gen Ryzen 7 chip than a previous-gen Ryzen 9 processor, because aside from the processors, the biggest difference between the HX77G and the HX99G are the prices.
The new Neptune is is available for $639 and up at launch. That’s the price for a barebones model and represents a discount (MINISFORUM says the computer has a list price of $799, but the company is constantly running sales, so it will most likely rarely actually cost that much).
MINISFORUM’s HX99G barebones configurations appear to be out of stock, so prices currently start at $927 for a model with 32GB of RAM and 1TB of storage. An HX77G with similar specs sells for $799.

Snazzy looking and price is not too bad. So tempting..
I have the HX80G, which also sports the same body and GPU, but has a ryzen 7 5800h, so a slightly worse cpu than either mentioned in this article, and I adore it. I’ll bang the drum for this line of thoroughly unique gaming pcs all day. If it’s in your budget, pull the trigger
