    Color: BlackStyle: Define R5Verified Purchase
    I finally hit the point of needing to replace the old case for my home computer, which had outlasted a couple motherboard/CPU combinations, and wanted a case that would be quieter, better fit the outsized heatsink fan/combo on my CPU, and be easier to work in. I'd narrowed it down to a short list, nearly got the Fractal Design Define R7, and then settled on the Define R5 because of the lower price and because the R7 would not have shipped for several weeks. I'm glad I went for this- the R5 is just the maximum size I would have wanted, and anything more would have been too large to comfortably fit the free space under my desk.

    When I got the Define R5 case, the first thing I realized is that it's the same case as my new computer at work; a bunch of our work machines were replaced with upgraded computers at the beginning of 2020, and I've been very happy with it there, so that was promising. Second thing I noticed was that the instructions were beautifully clear, in perfect English with good illustrations, making it much easier to go through setting up. (+ other languages, of course.) The third thing was, well, everything about this case.

    This is what people talk about when they say "Scandinavian design" - the focus on both function and aesthetics, with conscientious attention to even small details. It's all perfectly thought out, from the internal layout, the flexibility to change the layout around, the aesthetics even on the inside of the case, soundproofing, to cable routing and the careful selection of mounting screws and hardware - everything is incredibly thoughtfully planned.

    A few highlights:
    +++ Easy to work in - I've been building my own PCs since the late '80s (yes, really) and this is by far the easiest I've ever worked with in terms of how things go together.
    +++ The soundproofing is fantastic. As I sit here writing this review, I can't hear a single sound from this computer, unlike my old case. The case fans are completely silent, and the dampening on the panels cuts out any noise from the power supply.
    +++ Air flow is great - with just the two included 140mm fans, the board and CPU are staying cool despite moderate overclocking, but you could mount additional fans up to 6 more places if you thought you needed them. (3 top, 1 front, 1 bottom, 1 side panel.)
    ++ Good drive mounting - you could fit an absurd number of hard drives in here, and they have lightweight metal snap-in "sled" mounts to make it easy to fit them in place, with rubber grommets to absorb drive vibration; besides those, there are two special mounts for 2.5" SSDs on the back of the motherboard tray.
    ++ 2 USB 3.0, 2 USB 2.0 slots, plus audio jacks on front top of the case where they're easy to reach, and a nice-looking power switch.
    ++ Every mounting screw or component you will need, all good quality and black finished, with thumb screws wherever appropriate. There are rubber vibration-absorbing grommets for the hard-drive mounts, black cable zip-ties, and even a little plastic socket to slip over the hexagonal mobo mounting posts to make it easy to tighten them properly.
    + Cable routing options - several cut-outs with rubber diaphragms to let you route cables around the backside (right) of the case to keep them out of sight, velcro ties to pull them together; well-designed/routed cables to the front-panel switches, audio, LEDs, and case fan(s).
    + Alternative layouts - the instruction booklet shows you a number of ways you can change things around internally. Want the power supply on top instead of on the bottom? Want to mount a water-cooling system? Want to take out some of the drive cages, or reorient them? Want 3 more intake fans? There are a bunch of ways to do it.
    +++ Looks extremely classy, especially if you're into minimalist black monoliths, as I am. Blame the movie '2001'

    I can't think of many negatives, but for the sake of completeness:
    - The fan mount positions, especially the second front fan, really call for 140mm fans. I was going to stick a spare 120mm there but couldn't see how best to attach it. It's fine, as it's ended up not really needing it for airflow. I may buy another 140mm to add in later.
    - If you just have to have a 3.5" floppy drive or tape drive for old time's sake, you'll have to fit it into one of the two 5" optical drive slots. Sorry.

    This case is an excellent case. It has 2 USB2 and 2 USB3 in the front of the case. Which was a selling point for me. I wanted 4 USBs in the front and wanted at least 2 of them to be USB3. I love the case door that opens to expose the fans and the 5.2 drives. I.E the BluRay/DVD burner. Which it has 2 slots for. The door also can be reversed to open the other way.
    The material quality seems excellent. It comes with plenty of hardware for assembling. There is plenty of room on the inside for building. And plenty of places to tie off your wires. Along with nice holes cut out with rubber to run your wires.

    My only cons are this..

    The case comes with a switch to run your fans. I ignored this feature and ran my fans to the motherboard so I could control them. If you use the case, it seems to just be on and off, or there might be a off,low,hi type deal. But I chose to go the MB route.

    The sound is louder than I was expecting. This was sold as a quiet case. With sound dampening materials. But it is as loud as my old case. Even with the top covers in place. I can still hear my CPU fan going. One of the big reasons I went with this case was because it was suppose to be quiet. This one is in my bedroom and stays on at all times. So I wanted something that was going to be quieter than my old case. This was not. I wouldnt say it is extra loud. But it isnt as quiet as advertised.

    OVERALL..
    I would definitely recommend this case. If you dont care about the RGBs, or showing off the inside. This is a great case. If you need alot of spots for hard drives. If you want a case that helps keep the dust out. This is the case for you. It has 2 dust filters and the top of the case can be covered so dust doesnt fall into it.
    Also, it seems now a days. Cases are being made without the 5.25 drive spots. This has 2. You may not need a bluray burner. Or you can just get an external. BUT... That isnt the only thing these spots are for. If you would like to add an SD reader, a USBc, or just want to add extra USB spots. These can be used for that as well. Which is another reason I picked this case. So I can have a BR burner as well as a SD reader for cameras.

    The quality is very good and it has lots of good options for setting up everything you might need to put a PC together in. Good air flow, I did add 1 more fan at the bottom of the case and 1 to the front to create a good positive air flow to the case. I left the top plates on so all the air flows out the rear of the case. I have 2 GPU in the case and a wifi card and a sata x 4 control card and 4 spindle hard drives and 2 optical drives in this case and it runs cool. It's a very good design. I would definitely buy this again.

    5.0 out of 5 stars Replacement for my 15 year old case. It is even better in quality than the Thermaltake it replaces
    Reviewed in the Netherlands on July 7, 2022
    Color: BlackStyle: Define R5Verified Purchase
    The reason why I post this review is to correct some of the negative comments (reviews) I read.
    8 Motherboard standoff screws are included (ATX has 9 holes), because the MoBo positioning pin occupies the middle hole.

    I have one small issue. The case comes with 2 fans with only 2 pins, which means it has no speed control. All my other fans have 4 pins and daisy chain connectors, so I can vary RPM per group or single fan. My PC is always powered up, but it seems like it's OFF. It makes no sound whatsoever. Best case ever!

    The Fractal Design Define R5 case is excellent. It is the perfect mix of good airflow and sound proofing. I am a huge fan of its muted style. Nothing flashy, just quality. I upgraded from the Define R4 for my new build and I would confidently say that the R5 improves on everything.

    Workspace inside the case is great and even better if you remove the hard drive trays. I had no troubles building in it.

    The dust screens on the front and bottom are simple to remove for easy cleaning.

     SATAケーブルの配線では、マザーボードの方が6口ともひっついてあったので場所が狭く裏から線を出してきたケーブルを繋げるのに苦労しました。これは、マザーボードの方の問題ですね。
     また、ケース側面の蓋を取り付けると、すぐにネジが馬鹿になってしまったようになりました。しかし、3枚目の写真にあるように左右2個ずつのネジがあるのですが、右と左とで違いました。半分しかネジ山かないネジがあり、不良品だと思っていたら、それは、正面から向かって右側の蓋のネジだったのです。固定するところが少し山になった設計になっており、ネジ山は半分までできちんと止まりますので、不良品ではありませんでした。

    5.0 out of 5 stars Ottimo case
    Reviewed in Italy on October 23, 2016
    Color: BlackStyle: Define R5Verified Purchase
    Questo è il secondo cade della Fractal che acquisto, possiedo già un altro Pc inserito nel modello precedente (Define 4R) di cui sono entusiasta.
    Il nuovo modello migliora ulteriormente il precedente sotto vari aspetti in particolare ho apprezzato le seguenti migliorie:

    vani per Hdd/Ssd ancora più pratici con l'aggiunta dei 2 spazi laterali nella paratia di destra si possono installare fino a 10 unità da 3.5"

    copertura superiore smontabile a incastro rende molto agevole l'installazione di varie configurazioni di ventole/radiatori

    vano ventole anteriore più pratico nell'accesso alle ventole per manutenzione/pulizia

    Led di attività HDD !! nel modello precedente non c'è e non si riesce mai a capire se il disco lavora o meno!!

    la cosa che impressiona di questo case è lo spazio percepito e l'ottimizzazione interna!
    Nonostante il case sia un Midi Tower quando lo si apre e ci si mette le mani dentro, sembra essere molto più spazioso e di avere a che fare con qualcosa di più grosso, sicuramente merito dell'ottima costruzione e dell'ottimizzazione degli spazi di cui l'hanno dotato.
    Per farvi un esempio prima avevo un HAF X della cooler master che è grosso il doppio, ma dentro le periferiche erano "incastrate" peggio, per farci stare gli SSD dovevo usare dei vani doppi e alla fine avevo comunque un SSD a penzoloni fascettato...
    qui è tutto in ordine perfettamente disposto nel proprio vano e nonostante l'HAF X avesse un ventola da 30mm anteriore i dischi restano 9/10° più freschi nel Define.

    un discorso a parte invece per lo sportello anteriore.
    se da un lato apprezzo molto la possibilità introdotta dal nuovo meccanismo di apertura che consente di configurare lo sportello con apertura verso destra o verso sinistra, agendo sui supporti di contro perde quel effetto "WoW" che da la chiusura magnetica sostituita dal un gancio meccanico.
    è vero che in questa tipologia di case lo sportello anteriore di apre raramente giusto per usare un cd di tanto in tanto, ma preferivo il dovere fare quella leggera pressione per aprirlo e accompagnarlo solamente per la chiusura, rispetto al clack che fa quando lo apri e chiudi sul nuovo modello, tra l'altro la chiusura richiede una certa pressione o non si chiude adeguatamente.

    A livello di prestazioni sono più che soddisfatto, il case non solo rende il pc molto silenzioso ma ha un buon flusso di areazione, nal mio caso ho inserito una ventola da 14mm aggiuntiva nel vano anteriore (una noctua) e nonostante all'interno siano installati I7 4790, 5HDD, 3SSD, 1DVD e una 970 strix il pc rimane molto silenzioso e le temperature basse anche sotto sforzo. (ventole settate su velocità media)
    con configurazioni meno esigenti settando le ventole su velocità più basse il pc diventa quasi inudibile.

    Io son sempre stato un amante dei case Full Tower da gaming con ventoloni e ampi spazi, ma da quando ho acquistato il Define R4 per fare un server casalingo che rimanesse acceso 24/7 e non desse molto fastidio, beh me ne sono innamorato, linee pulite e sobrie, dimensioni contenute, solido (sembra un blocco di granito) e il rumore... se non fosse per il led blu non mi accorgerei nemmeno che è acceso.

    Ecco se proprio vogliamo trovargli un difetto è il peso, il fatto che sia solido come un blocco di granito fa si che pesi quanto un blocco di granito!!
    fortunatamente non sposto spesso il case...
