Chieftec Intros DT-10B-300 SFF Micro-ATX Case

Chieftec today introduced the DT-10B-300, a slim form-factor microATX case, with a volume of 8 liters. The case offers room for microATX (or smaller) motherboards, and even comes with a slimline optical disc drive bay. The case includes a pre-installed 300 W ATX 2.53 PSU that meets 80 Plus Bronze efficiency rating. Front panel connectivity includes three 5 Gbps USB 3.2 Gen 1 type-A, and a USB 3.2 type-C port. The case has vents along the front and rear panels, and a prominent intake along the left side panel that lets top-flow CPU coolers up to 70 mm in height take in air.

A detachable flexible storage caddie lets you mount a 2.5-inch SSD, a 3.5-inch HDD, and a 5.25-inch slimline optical drive. The case enables low-profile (half height) add-on cards of up to 14 cm in length, with this drive caddy out of the way. You get four such low-profile expansion slots. The case measures 294 mm x 92 mm x 341 mm (DxWxH), and is made of 0.7 mm-thick SGCC steel. The company didn't reveal pricing.

Cooler Master and Cryorig used to make similar slim cases with FlexATX PSU over a decade back.

Front port USB specs are off. Must be an error in the press release, because I've seen several other tech articles repeating it. From the spec sheet on the product page:
www.chieftec.eu/products-detail/668/DT-10B-300
1x USB Type C, 1x USB3.0, 2x USB2.0

Best I can tell looking at Chieftec's official pictures and their demonstration video, the USB-C and the USB 3.2-A ports use the same USB 3.2 Gen 1 motherboard connector, rather than a dedicated USB-C header connector. This means that the USB-C connector will be limited to 5Gbps connectivity speed. Having the C connector will be convenient, but disappointing for those who expect it to have faster transfer capabilities.

I really like the form factor, especially for work/business computers that do not need powerful graphics, but the general limitation of the front USB ports in these offerings is frustrating. Inwin had a line of slim mATX cases that had 2 USB 3.1 ports and 2 USB 2.0 ports, similar to this chieftec, but they were all USB-A. Unfortunately those are hard to come by now, and really overpriced when you do find them.

My ideal case would have 2 USB 2.0, 2 USB 3.1 A ports, and 1 USB 3.2 Gen 2 or USB 4 USB-C port. I'd be content to drop the USB 2.0 ports. Seems like the only way to get these is with a pre-build Dell Optiplex or HP ProDesk though.

Could have better front IO, but it's nice to see another super small MATX case out there. A pity there are so few LP cards these days worth a dang.

I like this case. Simple, clean and fit's a lot of standard parts! Nicely done @ Chieftec!

I do have a question about cooling though, with no grates on the sides I wonder if it won't turn into a hotbox of sorts. Likewise it doesn't look like there is much space for any case fans.

That's a good point. I think front fans added in would make for a reasonable cooling setup. The PSU fan will likely also contribute.

EDIT;
Just looked at the site page and watched the video and it doesn't seem like front fan mount exist. Shouldn't be difficult to add a 70mm fan in though.

Also noticing no reset button..

EDIT2:
Saw this one;
www.chieftec.eu/products-detail/528/BE-10B-300
And it's white version;
www.chieftec.eu/products-detail/651/BE-10W-300
These both have 80mm front fans which would be enough for whatever hardware one would fit in a SFF case. No front USBC though.

I like it! Great chassis for HTPC!
Most of these cases are miniITX, being microATX greatly increase the options. My current system is on a microATX board, unfortunately my blu-ray drive isn't a slim one...
