Jonsbo Announces the UMX3 Micro-ATX Chassis

Jonsbo announces the UMX3 micro-ATX chassis. With the UMX3 we present an appealing case for customers who are looking to install a powerful system based on a Micro-ATX board. The high-quality case features a timeless design with a very attractive, classic exterior that blends harmoniously into any interior style. The UMX3 can easily be equipped with ATX power supplies. In addition, four PCI expansion slots for the installation of VGA- or sound-cards are available. In spite of the compact dimensions, large CPU-coolers and long VGA-cards can be fitted inside the case.

The Mini-Tower combines a steel chassis for maximum stability with an extravagant designed exterior, where the smooth curves of the case will automatically draw attention. The exterior hull of the UMX3 is made of 2 mm strong, high-quality aluminum. The interior of the UMX3 has been designed for maximum compatibility. The power supply is mounted behind the case front on a specially designed frame. The power supply is looped to the rear of the case. The hard disks are mounted at the bottom of the chassis.
Micro-ATX or Mini-ITX motherboards can be installed; 4 PCI expansion slots are available at the rear for the installation of appropriate cards. The UMX3 can be equipped with CPU coolers of up to 163 mm in height, as well as VGA cards with a maximum installation length of 320 mm.

A HDD-cage is located at the bottom of the case, which can hold up to three 2.5 inch drives. Another 2.5 inch or a 3.5 inch HDD can be installed on the bottom plate. Externally, 2 x USB 3.0, 2 x USB 2.0 as well as HD audio connectors are available.

The UMX3 in black and silver is now available in stores. The MSRP for the windowless variant is 119.99 Euro (incl. 19% VAT). In addition, a version with an acrylic side panel is available. The MSRP for this is 124.99 Euro (incl. 19% VAT).

Looks good. Like full window side panel. But, does look just like the cases Rosewill has been selling on Newegg for a while. Probably the same OEM.

Ah, am I the only one who would detest the idea of the PSU still discharging heat into the case?

Why not place the PSU at the bottom and have it blow out from the raised underside? I'd say then have snap -on plastic side panels the channel that exhaust along the bottom then with gill like vent the have the air exit the back and not toward my work space. While I realize that kills long graphics cards, might be a good thing, as with all that heat recirculating most enthusiast builds I'd imagine might commit hari kari soon enough.

I would rather be a front grill/vent that permits the PSU to flip around and draw air from the front. Then move the drive mounts where the PSU was along with the I/O buttons and USB, that could free the bottom for another fan mount.

Looks like a nice case but you'd surely want a modular PSU with that kind of layout.

Nice looking and well-built case, reminiscent of the pre-2013 Mac Pro, whose design I always liked....

But like others, I am leery of the top/front mounted PSU.....I don't relish the idea of not having any fresh air intakes on the front of the case, and do not want to pull hot air from the PSU through directly onto the cpu area. No wonder it is shown with a monster sized tower cooler... Plus I think it would make the whole machine to top heavy for most people's liking........jmho though :D

But it's not is taking the air out the side of the case, how ever what bothers me is that the PSU be sucking the heat from the CPU.


Shame it's so small and would like to see a much bigger version of this.

Personally i am suck of the PSU at the bottom tbh and not a fan of it what so ever, i would like it if they would place it at the top sideways.

Well having the PSU suck air off the CPU is almost as bad as having the CPU suck air off the PSU. Both of them will die a slow, painful death if subjected to excess heat.

I would like a bigger version also, but not unless it had the PSU somewhere else, otherwise it would still SUK, just alot more than it's little brother....

Might was well buy a Carbide AIR 540 and be happy.... NO PSU/CPU heat issues whatsoever, since they are separated by a divider. Not quite as pretty as this case, but a whole lot cooler all the way around :)

Oops must of been thinking one thing and typing another but all so see it as a issue that's why i said it ;), PSU is not putting heat in to the case but taking heat from the CPU and though the PSU out the side of the case.

Honestly that's not a problem. PSUs (good ones at least) are designed to pass the ATX specifications which originally intended to use the PSU as a CPU heat exhaust.

Most high-end PSUs are rated at 40C or 50C temps, which are way over the ambient temp that you'd see in a case with good airflow.

I like this little thing but I think it's amusing how they didn't show any of the PSU cables at all. I wonder why....

Look awesome, reminds me of InWin, but I don't mind that. At 130 EUR though, I think I am gonna pass.
