Thermaltake’s Core G21 TG is a modern case for the mainstream

When you hear "Thermaltake", "understated" is probably not your word association go-to. The company sells a substantially wide range of cases, though, and its new Core G21 TG Edition is pretty restrained. Were it not for the solid sheets of tempered glass bolted to the sides, this ATX mid-tower chassis would barely stand out in an office, much less in a game room or a LAN party.

Despite the low-key appearance, this case has a thoroughly modern design. It supports Thermaltake's latest cable management design, and it also gets the company's "LCS" certification that marks it as ready for liquid-cooling enthusiasts. The bottom of the case is shrouded to hide messy wiring and to separate the power supply from the hot components above, like most current case designs.

Meanwhile, all of the drive mounts in the Core G21 can behidden behind the motherboard tray. You get two dedicated 2.5" hardpoints, and two more that can take a 2.5" or 3.5" drive. The 2.5" drive sleds can alternatively be installed on top of the power supply shroud. Hiding away all of the drive mountings leaves plenty of room in the main area of the chassis for graphics cards up to 16" (41cm) and plenty of liquid-cooling hardware.

Builders can mount three 120-mm fans or two 140-mm spinners in the front of the case, an additional 120-mm or 140-mm fan in the top, and a further 120-mm fan in both the bottom and rear of the case. Thermaltake helpfully includes a 120-mm exhaust fan in the rear spot. Liquid-cooling fans might be pleased to hear that the Core G21 includes specific mount points for a reservoir toward the front of the case, and that they can install a 360-mm or 280-mm radiator in the front, as well as a separate 120-mm unit in the rear.

Unfortunately, we don't know when the Core G21 TG Edition will be available, but Thermaltake says it will be available for online ordering "soon" and that it should be "budget friendly."

    Is it just me, or does that water cooling + cabling job look really, really bad? The color coordination is nonexistent (lime green coolant, black and yellow cabling, a grey and gold motherboard, red RAM, and fully rainbow-tastic fans?), the runs are neither straight nor symmetrical, and it all has this “we struggled to make this actually fit in here” look to it. I mean, what is up with the oddly sinuous thingy connecting the rad to the res? I get that that would be a really tight bend if it went straight up, but why not then use a thinner rad or just mount the res a little further back?

    I mean, if you go to the massive effort of setting up a hardline liquid cooling setup for your promo pics, at least do the extra 10% work to make it look OK.

    Lther than that, it looks like an okay case, except perhaps for the fact that it looks like the radiator fans are mounted between the front fascia and the case, and that it doesn’t seem to filter the intakes at all.

        This case is much more egalitarian than that. It lives in the [i<]"I don't [u<]see[/u<] color, brah!"[/i<] space. Of course, the phrase "I don't see color" indicates an intriguingly broad range of possibilities including (but not limited to): a.) I'm a narcissistic, manipulative, alt-right control freak who is entitled to dictate the terms of "reality". I will dismiss both your argument & your right to a voice through any lazy & inane tool I make up. b.) I'm basically a nice person & all this stupid arguing makes my head hurt c.) I have achromatopsia & as far as I'm concerned, you are gray. (Don't even ask "What shade?")

      Standard Tt lack of attention to detail:

      Colours don’t match (ugh)
      Pipes aren’t straight (my OCD is twitching)
      Random use of nickel-plated right-angle adapters in an acrylic loop?!
      Components are mismatched and outdated (LOL at the 40GB RAID setup)
      Inconsistent demo build wiring – front panel, fans, GPU, motherboard wired up, but no power or data to drives
      Seemingly no fan filters or access to them, but a window to display all the dust and crap that gets in.
      Drives are mounted backwards (middle picture) so the thumbscrew would prevent you from connecting cables anyway.

      I can only assume that the marketing goon responsible for producing these product shots has no idea how to build a PC, which seems pretty shortsighted and stupid for a company that solely manufactures components for the PC builder market.

    Personally I would not call a case with a glass side panel “low key”. Maybe I’m just old-fashioned.

      Hey, this is Thermaltake we’re talking about. 😛

    Wowee, a matched pair of WD 40GB drives – where have they been hiding those?!

      Maybe Starfalcon has been supplying them with parts for their photo shoots.

      They found them hidden in the bottom of their jumbo box of jumpers.

    How would one clean the intake filters?
    There [i<]are[/i<] intake filters, right?
