This one is for people who've already decided they need GB300-class hardware and want to know two things: which tower to buy, and whether it will behave the way the spec sheet implies. I've gone through the most detailed hands-on reports I found, ServeTheHome's eight-page review of the GIGABYTE W775-V10-L01 and Harrison Kinsley's testing of the ASUS ExpertCenter Pro ET900N G3, along with every DGX Station spec table on Newegg.
What the Deep Dives Actually Found
Memory isn't one flat pool. ServeTheHome notes that NVIDIA reserves 16GB of the Grace memory, leaving 496GB. Kinsley measured a pinned LPDDR5X copy at 149GB/s with 32 threads, roughly 300GB/s of combined read and write traffic, against a 396GB/s spec. ServeTheHome found that feeding the GPU from LPDDR5X over NVLink-C2C beat running a model on the CPU directly, but its conclusion is clear: keep decode in HBM.
Power is a shared budget. ServeTheHome saw the Blackwell Ultra GPU idle around 148W with a 1.3kW cap, and the Grace module capped at 300W, all inside a 1.6kW ceiling that also covers the NIC, cooling, NVMe drives and any add-in card. Kinsley's ASUS unit reported a 1,300W GB300 power cap, active for about a third of his test run. It wasn't a thermal limit, though: the GB300 peaked at 75°C with zero thermal slowdown events.
The networking is unusual. The GPU reaches the ConnectX-8 over PCIe Gen6 x16, and ServeTheHome measured 784.3Gbps between the GPUs of two stations. The Grace CPU's link tops out near 229Gbps, so scale-out traffic should come from the GPU side.
There are hard limits. FP64 is 1.3 teraflops. The LPDDR5X SOCAMM modules aren't user-serviceable, according to ServeTheHome. The three PCIe slots hang off the Grace CPU, so any card you add needs Arm Linux drivers that work on Ubuntu 24.04.
Head to Head: The GB300 Towers on Newegg
Because NVIDIA supplies the motherboard, the differences come down to chassis, cooling, storage configuration and management extras.
| System | Storage as listed | Cooling | Operating temp | Standout |
|---|---|---|---|---|
| ASUS ExpertCenter Pro ET900N G3 | 4x 2TB PCIe 5.0 (2x 2TB version also listed) | Single-piece cold plate, four side fans | 10°C to 35°C | ASUS Control Center Express clustering |
| GIGABYTE W775-V10-L01 | 2x NVMe | Two 360mm radiators, leak detection | 10°C to 35°C | 44 to 46 dBA at full load (ServeTheHome) |
| MSI XpertStation WS300 | 2x 2TB RAID 1, two open PCIe 6.0 x4 slots | Liquid cooling module | 10°C to 30°C | IPMI 2.0, Redfish, TPM 2.0 |
| Supermicro ARS-511GD-NB-LCC | 2x 1.92TB plus 2x 960GB PCIe 4.0 | Closed-loop liquid cooling | 10°C to 25°C | 5U rackmount option |
The Rankings
1. GIGABYTE W775-V10-L01: Best Overall
The GIGABYTE W775-V10-L01 is the most thoroughly documented of the four, and what's documented is good. ServeTheHome measured 36 to 38 dBA under lighter loads and 44 to 46 dBA at full load, credited its high-end liquid cooling, which uses two 360mm radiators, and found leak-detection sensors that shut the system down if a joint drips. It also runs OpenBMC with an HTML5 remote console. At about 64 pounds, it's a two-person lift. One disclosure: GIGABYTE loaned ServeTheHome its unit, and STH labels the review sponsored, just as ASUS loaned Kinsley his.
2. ASUS ExpertCenter Pro ET900N G3: Best Out of the Box
The 4x 2TB ASUS ExpertCenter Pro ET900N G3 fills all four M.2 slots from the factory, and ASUS adds Control Center Express for clustering several units. It's the model line Kinsley tested (his unit came with an RTX PRO 4000 SFF for display), and he says he'd recommend a DGX Station over a four- to six-card RTX PRO 6000 build for professional use. If you plan to add your own drives, the 2x 2TB version leaves room.
3. MSI XpertStation WS300: Best for IT-Managed Fleets
The MSI XpertStation WS300 boots from two 2TB drives in RAID 1 and leaves the two PCIe 6.0 x4 M.2 slots on the ConnectX-8 open, with heatsinks for all four. Its AST2600 BMC runs AMI MegaRAC firmware with IPMI 2.0 and Redfish, and MSI lists a hardware root of trust and TPM 2.0; the mirrored boot drives are what set it apart for IT teams. The trade-off is a 30°C operating limit.
4. Supermicro Super AI Station: Best for a Rack or Lab
The Supermicro ARS-511GD-NB-LCC can be fitted with a rackmount kit to run as a 5U system and uses a Titanium-rated 1600W power supply. It has the tightest operating limit here at 25°C, weighs 88 pounds, and its listing ships with PCIe 4.0 drives, so I'd see it as a lab or server-room machine rather than a desk-side one.
The Card I'd Add
Kinsley's DeepSeek-V4.1 Flash setup used an RTX PRO 6000 to hold cold experts, and he recommends one over the RTX PRO 4000 his unit shipped with. Because add-in cards draw from the same 1.6kW budget, I'd pick the 300W RTX PRO 6000 Blackwell Max-Q over the 600W Workstation Edition.
Who Should Buy One, and Who Shouldn't
Buy one if you serve models to a team or run agents around the clock, if your models need more than the 192GB a dual RTX PRO 6000 workstation offers, or if you want server-style management in an office. ServeTheHome describes it as a high-end developer workstation that can serve the local AI needs of a workgroup, and that matches what both reviews measured.
Skip it if your work is FP64-heavy. If your models fit in 192GB, an ABS AI Workstation with two RTX PRO 6000 Max-Q cards runs familiar x86 software. If you're still learning, an ASUS Ascent GX10 runs the same NVIDIA software stack. And if you need Windows on day one, NVIDIA says the Windows edition is coming in the fourth quarter of 2026.
Frequently Asked Questions
Which DGX Station tower is the best? They share NVIDIA's GB300 motherboard, so it depends on priorities. I'd pick the GIGABYTE W775-V10-L01 for a quiet office, the 4x 2TB ASUS ExpertCenter Pro ET900N G3 for storage out of the box, the MSI XpertStation WS300 for IT-managed fleets and the Supermicro for a rack or lab.
Do all DGX Station systems perform the same? The core silicon is the same because NVIDIA supplies the motherboard. Differences come from cooling, storage, power supply and management features. ServeTheHome's GIGABYTE showed a 1.3kW GPU power cap, and Kinsley's ASUS unit reported a 1,300W GB300 cap.
Can I upgrade the memory in a DGX Station? No. The GPU's 252GB of HBM3e is part of the chip, and ServeTheHome reports the 496GB of LPDDR5X SOCAMM memory is not user-serviceable.
How fast is DGX Station networking in practice? ServeTheHome measured 784.3Gbps between the GPUs of two stations over two 400G links, while the Grace CPU's link to the ConnectX-8 topped out near 229Gbps.
Should I add an RTX PRO 6000 to a DGX Station? Harrison Kinsley recommends an RTX PRO 6000 over the RTX PRO 4000 his ASUS unit shipped with, and used it to hold cold experts for DeepSeek-V4.1 Flash. Because add-in cards share the 1.6kW budget, I'd choose the 300W Max-Q edition.
