Apex’s DM-387 case is a great choice for instances where you don’t have a lot of space for a system. It would work well in kiosks or as a video wall controller. You could also use it to control information signs in a hotel or airport. Its small size would also make it a good choice for an HTPC.

The drive bay housing tilts up for easy installation. There are two external bays, one 5.25” and one 3.5”. There is also a 3.5” hard drive bay. The front panel also has two audio jacks and two USB ports. Once everything is installed put the lid back on and you’re good to go.

  • newegg Stands Horizontally or Vertically The Apex DM-387 can be laid horizontally on your desk or vertically on the floor with the included stands to fit your working space.
  • newegg Convenient Front I/O Panel The Apex DM-387 features a convenient front I/O panel for easy access to two USB 2.0 and two audio ports.
  • newegg Built-in 275W PSU The Apex DM-387 is equipped with 275W power supply unit to handle typical power consumption for most MicroATX systems.

3 out of 5 eggsPower Supply Woes

Pros: Great design, stylish, not a difficult build, people like it.

Cons: The power supplies have been a problem. I've ordered 20 of these so far this year and 4 power supplies have failed on the build bench and another in a customer's home. That's a 25% failure rate - not acceptable. The only way to RMA the power supply is to RMA the whole case. Once the build is done, who wants to go through that.

Other Thoughts: A replacement power supply is available and has been, so far, very reliable: SL-300TFX - use the method of your choosing to search for it. They're about thirty-five bucks.

5 out of 5 eggsGood HTPC case

Pros: Great size for my HTPC. I've been using it for around 6 months now.

Cons: Sparse instructions for getting it all set up.

Other Thoughts: I have two hard drives mounted and a Blu-Ray drive. No problems so far.

Well worth it in my opinion

3 out of 5 eggsMixed feelings

Pros: Case itself is fairly nice.
Most edges rounded nicely.
Drive cage lifts out for ease of access.
Fairly good layout for cooling.

Cons: The power supply is a piece of cheap junk. Have had *3* of *5* die in the last 3 years, 1 in warrenttee the other two somewhat out.
The case fan is badly positioned, blocks some access to the 3.5" slot and if you upgrade the PS to a GOOD ITC power supply you have to remove the case fan entirely to fit the PS.

Other Thoughts: There is no excuse for using SLEEVE BEARING fans for the case fan or in the PS - one PS appears to have died after the CHEAP fan froze up due to rapid wearout of the bearing, have had to replace 2 of the case fans so far due to rapid wearout. If I could get JUST the case with no PS at half the price I'd like this case a LOT better.

4 out of 5 eggsNot a beginners case but a good one.

Pros: Drive cage lifts right out. Tons of room for a mini-itx mobo. Power supply handles a Nano dual core, card reader, dvd burner, HD and e-Sata drive with no issues. Doesn't take up much space.

Cons: The only real con I have with this case is that they designed it to take an old, bottom mounted, 3.5" floppy instead of a card reader! What I mean is that there's NO provision for mounting a reader at all. Why?

Other Thoughts: What I wound up doing was using a large screw in the back hole of the card reader to keep it from falling into the case, then using another screw with a large head to clamp the reader to the tab of metal near the forward screw hole. It works just fine this way and is secure, but it lost an egg thanks to this.

Actually, since I do like messing with cases so much...maybe I should give it an egg. :) It's not a case for someone that wants everything to fit perfectly from the get-go, but is a good one.

2 out of 5 eggsVery mixed experience...

Pros: - Small half-depth case that fits MicroATX motherboards.
- Quiet (nearly silent on my desk next to my monitors).
- Good ventilation and airflow.
- Handy, easily-removed, drive cage.
- Cheap.
- Not a box of razors like other cheap cases.
- Nice magnetic door closing for the front.
- Lights on the front are visible through the door, but not painfully bright at night.
- Single thumb screw for the side.

Cons: - Considering the drive cage has probably over 100 complex holes for ventilation, there is only one spot you can install an SSD. There is plenty of room for at least 3-4 of them inside if it just had the holes. Since I used these at work and had no interest in drilling holes myself, my SSDs are zip-tied together and attached it to the only available mounting location.
- The first one was perfect, but the second one had a motherboard tray (which is not removable) that was offset about half an inch down in relation to the outside of the case, so the motherboard and IO shield do not mate up correctly. This is a severe flaw that I would return it over if it probably wouldn't cost as much to ship it back as it cost to buy. Really bad QA/manufacturing.
- Front ports are USB 2.0, not 3.0... They're also upside-down.
- As mentioned elsewhere, the top exhaust fan could move forward with no ill effects to allow for larger power supplies.
- On the one I tried to install a DVD drive in, the cage kept the drive from inserting all the way. I have no clue why it had that stop in there.

Other Thoughts: The first one was my development box with an i7-4770S and 2 SSDs, all of which barely gets warm in there. At full load the exiting air is not much above ambient and the processor rarely bumps over 60C. At idle it runs at only slightly above ambient. That one went together perfectly, aside from the lack of a second place for an SSD. It'd be worth investing in a 3.5" to 2.5" adapter if you plan to use 2 drives if you want to make it all clean.

The second was a mess. The audio jacks are tight up against the bottom of the IO shield opening without the shield simply because I had no other choice short of burning money on a return or ordering another case. I gave up on the DVD drive, which I scavenged from their former PC and they never use anyhow. The upshot is that it runs just as cool as mine and the total price for the PC was very reasonable.

Since this price range is pretty packed with options in the MicroATX and Mini-ITX form factor, I'll get another case for my next build. I wish others put a fan on top like this one, though.

4 out of 5 eggsGood functional case.

Pros: Good value, quiet setup/fans and decent quality for the price.

Cons: Cable management is cramped but I suppose it has to be with the small size of the case. Plastic is kind of cheap but not to the point where it's going to break too easily.

Other Thoughts: Everything is pretty intuitive with hardware install. Not a bad little case overall. I'd probably purchase it again.

4 out of 5 eggsGood case PS so-so

Pros: Easy to work with internal layout for such a small case, edges NOT sharp unlike many cheap cases. Vent positioning works with every MB I've used it with.

Cons: Had one power supply die young a couple years back, most of the rest have lasted years without issue. Fan in the PS is thin and marginal.

Other Thoughts: Overall one of the best cases I've ever dealt with in decades of computer building both personal and professionally.

3 out of 5 eggsGreat HTPC case but not a solid PSU

Pros: Excellent cable management, airflow, and appearance. Things are tight inside but everything has its place.

Cons: The small power supply unit that came with this case worked great for quite a while but is now dead after just over 3 years of light use.
