Antec P101 Silent Performance Series Mid-Tower PC Computer Case with Sound Dampening Panels, 4 X 120/140mm Cooling Fans Pre-Installed

The stand-out thing on this model is the dust filtering. I've bought several other brands, some of which force you to pay extra to buy an accessory dust filter kit, none of which are as fine in terms of particle filtering or fit as well or clean as easily as the front filter on this unit. The front dust filter is just about the finest without being incredibly restrictive of air-flow that one can get and in my dusty home that's pretty useful. It also simply slides out and can be rinsed or wiped down.The sound dampening is also pretty good, the isolation of hard drive noises from multiple spinning disk magnetic drives, including enterprise drives is also quite good, probably not as good as be-quiet with their specialized isolation caddies but it's a lot cheaper. The hard drive caddies themselves are plastic, not too impressively built, kind of cheap but they work, don't transfer vibrations that badly so I can't complain that much, certainly not for anything in the sub $150 range as far as cases go.Airflow is good, for a media server build the fact that the hard drives are located in the front directly in the path of airflow is great because I want to keep them above all else cool so they last longer. It is a rather simple design, most PC's I've built for gaming have either top and/or bottom fan mounting options but this is a simple straight-through.The default fans after nearly a year of constant use aren't suffering any whine or annoying noises, if they do fail I'll just replace them with some Noctuas. The front 3 fans at least aren't PWM (back one is), so you can't control them with software or the motherboard with temperature targets, instead they're controlled with a switch on top which has high, low, and off settings. On high they're noticeable in quiet scenes when a movie is playing on my nearby TV but on low they're not really noticeable and wouldn't bother most people trying to sleep in the same room as them as long as you're at least 8 feet away. Lack of PWM on default case fans on a budget case is to be expected, par for the course. If you want that buy aftermarket. Noise level could probably be lowered a bit from these or I could increase the air movement without raising noise level if I replaced them with Noctuas but once again the noise isn't annoying on low with no other sounds around. If I wanted to really run them at full speed all the time I'd definitely replace for the sake of my movie-watching experience them but a lot of people could probably tolerate even that.Cable-management is fine, there's plenty of room for routing things neatly and cleanly and building was not a struggle.One potential annoyance for some people may be the glowing white lights around the USB ports at the top of the case. I could certainly do without it but it's not so annoying that I've sought to try and disable it, suppose one could take nail polish or similar and carefully paint over the lights with it. The hard drive access light at the top blinks like crazy for a media server build like mine so I ended up covering it up with a piece of black electrical tape. Not sure why those types of lights still exist or can't at least be disabled in UEFI/BIOS.

I use this case for a workstation with 9 storage drives, and I encountered many thoughtful features when building in this case:1) Drive cages - The drive cages in the front of the case are oriented such that drives end up with their connectors accessible from the right side of the case. This leaves an pleasantly short and direct path to route SATA power cables from the PSU and SATA data cables from the motherboard. Furthermore, you don't have to worry about anything in the main compartment of the case (the section that houses the motherboard, which is behind the drive cages) interfering with swapping hard drives in and out).2) Drive trays - It is very simple to install 3.5in drives into the toolless drive trays. The flexible trays have plastic pins on the inner sides that plug into the screw holes of the drive to secure it in place. 2.5in drives sit flush once they are screwed in from holes in the bottom of the tray. The tray's holes are the perfect distance apart, so it is easy to align the drive's screw holes with the tray's holes.3) Motherboard tray 2.5in mounts - Two removeable foam-padded 2.5in drive trays slide onto rubber mounts behind the motherboard tray for easy installation.4) Rear-inserted power supply - Being able to remove and insert the power supply from the rear of the case allowed me to simply slide the power supply out to connect an additional power cable when I added more drives to the case.5) Power supply shroud cable cutouts - This case has many cutouts for cable management. In particular, it has cutouts near the bottom of the motherboard tray and cutouts on the top of the PSU shroud that make it easy to route cables to the graphics card and lower motherboard connectors.6) Fans and fan controller - The case conveniently comes with all of its fan slots fully populated, so I do not have to buy and install additional fans. Furthermore, they come connected to a series of molex connectors that lead to a fanspeed controller at the front of the case. All you have to do to power the fans is connect the case's assembly of fan wires to two molex connectors from your PSU.7) Socketed side panels - The side panels are attached to the case by hooking the front ends into slots near the front of the case and popping the rear ends into ball sockets (I don't know the name for such a fastener) near the back of the case. This makes it easy to properly align the side panels with the case when installing them, and it also leaves the side panels flush with the case even without fastening the thumb screws in the rear of the case.8) Included port plugs - The case comes with silicone (or rubber?) plugs for the front IO ports located on top of the case. Dust and particles really do accumulate in unprotected upward-facing ports over time, so I find it convenient that I do not have to purchase a separate set of plugs.9) Reversible front hinge - You can change the direction the front panel swings open for your convenience.10) Noise dampening - both side panels and the front panel are padded with foam. Furthermore, the top of the case has no fan mounts or other openings and is completely lined with foam. This makes my computer very quiet, even when FFmpeg has each of its 22 hyperthreaded cores are under full load.11) Manufacturing tolerance - I am convinced that this case is manufactured under very tight manufacturing tolerance. When I slotted my graphics card into my motherboard, the holes in my card's PCIe bracket aligned perfectly with the PCIe mounting holes in the back of the case. Furthermore, the mounting holes in all the drive trays are just the right size for screws to fit snugly, making it easy to align a drive's mounting holes with the tray.My list of appreciations is already long, but there are so many more minor things I like about this case, like the visual aesthetics, bottom clearance, and fine fan filters. I haven't discovered anything I don't like about this case, but I hope my review helps you know what kind of building experience to expect from this case. I look forward to this case becoming popular and influencing the design of quiet home workstation cases in the future.
