Review: 2U cases are designed for a limited foot print and you should only buy this case understanding that: 1. You will be limited to a CPU cooler height of <70mm. 2. There are limits to the size of Power Supply you can use. Most rack cases require you to buy a special form factor of PSU. This one can fit a standard ATX PSU under 160mm in length, so an 850W will fit no problem. 3. No rack case comes with rails - it's always something you need to buy extra, with much more expensive cases (not saying this is good, but it is the reality). 4. Only low profile expansion cards are supported. The user who left this review would have been better off buying a 4U case to convert their desktop over to rack mount. That being said, what this case does, it's very good at. You can fit an ATX mobo/PSU inside, which is hard to find for a home lab. It's got excellent airflow (front to back) for cooling. Convertable 5.25" bays for more drive storage. It's great bang for your buck. Comparable cases from Supermicro are 2x-3x the price. Review: This is a great case, it does not require an SFX power supply and it supports a full size ATX motherboard. That's the punchline, folks. If you want a 2U case you're either dealing with SFX power supplies or ITX / mATX boards. Not with this case. You can use nearly any PSU you want. And considering you could never use 1300w of components in this case, this is a non-issue. 850W Seasonic? Easy. They put the power supply in the front of the case, which yeah, is arguably weird. But if it was in the rear you could not have an ATX board. Or they could have tried to smush an SFX in there or used some proprietary PSU but that would be awful. This is the best of both worlds. And yes this does mean there is an auxiliary power cable going from the rear to the front, and it requires a somewhat sharp bend to plug into the PSU but when you properly disassemble the case and carefully bend the cable its no big deal at all. And yeah, you gotta buy a 2U cooler. Its a 2U case afterall... While there are some low profile coolers that would work, you don't really want the airflow going that direction in a 2U case. I even created a custom magnetic dust filter for the front which makes it even better. Great case. ## Features - Supports ATX power supplies of up to 180mm depth - Supports 1 x 2.5" SSD and up to 5 x 3.5" HDD - 5Gbps USB 3.1 Gen1 interface (downward compatible with USB 2.0 & USB 1.1) - Dual 5.25" expansion bay brings flexibility in installing 5.25" devices - Built-in fan bracket which supports up to three 80mm x 38mm fans - Supports up to ATX (12" x 9.6") motherboard - Supports 7 low profile expansion slots - Reserved mounting holes for sliding rails which can be easily installed.

Great case. ### ⭐⭐⭐⭐ Review *by D***. on 10 July 2024* I have purchased three of these cases and it's a good design overall. The only reason I don't give it 5 stars are the holes cut on the top of the case for venting the power supply don't seem to line up with the ATX power supplies I keep buying. Not enough to worry me, or make the units over heat, just enough to make you scratch your head and wish they were 1" shifted. ## Frequently Bought Together - SilverStone Technology 2U Dual 5.25" Drive Bay ATX rackmount Industrial Storage Server Chassis with USB 3.1 Gen1 Interface, SST-RM23-502 - SilverStone Technology RMS03-26 Tool-Less Ball Bearing Sliding Rail kit for rackmount Chassis, SST-RMS03-26, TAA Compliant - Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/503817286-technology-2u-dual-5-25-drive-bay-atx-rackmount-industrial](https://www.desertcart.us/products/503817286-technology-2u-dual-5-25-drive-bay-atx-rackmount-industrial) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
