  1. Hello, im trying to build a pc for my sister and she wants a more girly (white and colorful) pc unlike mine lol Do you know if any of these parts come in white or if they are only black? I found a Cooler Master MasterBox TD500 Mesh White and Crucial Ballistix RGB 3600 MHz DDR4 DRAM but I’m having trouble finding others. Thankyou for any help or advice you can give!

    1. Post

      Hi Renee,

      Good on you for building a pc for your sister! The Cooler Master Masterbox TD 500 is a good choice for a case and the Ballistix RGB 3600 in white as well. I literally also just got an e-mail with NZXT announcing a bunch of white products, so you could probably check those out as well: https://nzxt.com/collection/make-a-splash – albeit they are a bit expensive, but if you’re in need of a cooler like the Kraken RGB or some case fans as well in white.

      Corsair also sells some white PSUs, like the CX650, which is fully modular and also rgb, although it would be covered a tad by the bottom cage in the TD500 case.

      For a motherboard, this one might be a toughy if we are talking about the build above and may be dependant on what you have to spend. The ASRock B550M Pro4 might be a decent choice for a budget option, not all white but definitely has white tones for about $94 and the whitest B550 motherboard you could get would probably be the NZXT N7 B550 – but very expensive ($254).

      And finally, the hardest pasrt may be getting a white theme gpu, as they are already hard to get priced well at the moment and it would depend on what you get. Such as the 5600 XT above will be quite hard. However, there are some higher end RX 6700 XT’s available, and there are options like this Power Color one in white on amazon – https://amzn.to/3Azzdkj

      I hope this helps and look forward to hearing how it goes!

      Hi Eric, you definitely can – the Ryzen 3600 and RX 5600 XT GPU are very capable. It doesn depend on your stream setting and such, but you’ll get the idea if you google “streaming with a 3600 and 5600 XT”. Best of luck building your PC!

      This is the real reality right now with GPU shortages. You have too search a little bit for what’s there, as it’s hard to predict what’s available.

  2. Hi! I was looking for a 800-900 PC budget and I was wondering if replacing the CPU and GPU with an “Intel Core i5-11400f CPU” and a “Nvidia RTX 3060” would work well with the rest of the set-up. Thank you.

    1. Post
      Author

      Hi Jorge, The RTX 3060 for sure is compatible and you can get an Intel Core-i5 10400F too, but if you get that CPU you will need to get a motherboard that’s compatible, such as Intel B460, B560, H410, Z490 or Z590.

      The cheaper ones are the non “Z” versions, however they still cost a little over $100, so that will cost you a bit more. My suggestion would be to go with a Z490 Chipset Motherboard, as you can utilize memory speeds of at least 3200mhz, so that it would have comparable performance to the AMD 3600 in the build above.

      I hope this helps!

      Hi Brian, these are refreshed at the start of each month, and unfortunately all graphics cards are extremely low on supply right now (for various reasons like crypto mining etc.) causing people to scalp and inflate costs. I do note that the you shouldn’t be spending anymore than $50 more than that card, otherwise you might have to look into the alternatives listed above (GTX 1660 Super, GTX 1660, or RX 5500 XT 8GB). I hope this helps!

      Hey Doug, it was priced at the start of Jan, so I’ll be refreshing these shortly to reflect current costs for February. Hardware prices have been a bit chaotic (especially GPU’s).

  3. Hello , this will be my first time building a pc and was wondering I could use a NZXT H510 case instead as I prefer the colour scheme? Also anything you would recommend to first time builders?

    1. also was wondering if any other graphics card was good as currently they’re all out of stock and if the thermaltake TR2 series 700 W was a good power supply to use instead?

      1. Post
        Author

        Hi Robbie! First, the NZXT H510 will work perfectly and is a good case and the Thermaltake TR2 700W would work too and has more than enough power though. I would search for other models of the 5600 XT or you could see if there are GTX 1660 Super’s available as an alternative too. I hope this helps!

    2. Hello, i have a 1660 super single fan, and i still need to pick up a motherboard and CPU. I am wondering if i need another PSU because the one i have is 350W. Will it work with this build?

      Hi Renee,

      That build would work perfect and all is perfectly compatible! And it should perform pretty good in most games as well at 1080p.

      Best of luck building!

      1. Thank you so much for the feedback! I have another question if youre able to help. I’m running into a problem with the Video card i listed being out of stockseemingly all the time at the moment. Is there another Video card i could use in place of that one that would be just as good or better?

        1. Post
          Author

          Not a problem! And ah, now that’s the real question right now. Graphics cards, of all types right now are simply low in supply. It’s sort of this trickle down effect from a bunch of newer cards that got bought out and the holiday season just passing. To be honest I just be looking for alternative brands of GTX 1660 Super’s or AMD RX 5600 XT’s as your best bet. Hopefully cards start replenishing soon here.

  5. Hi Corey, first timer here. A quick question about PC cases; would any ATX or MicroATX tower work for this particular build? The Cooler Master doesn’t look bad by any means but I kinda prefer the NZXT case you listed for the $1000 build and I also quite liked the Corsair Carbide Series 275R as well. Thanks!

    1. Post

      Kartik – great question. Yes, most ATX and Micro ATX cases will work, since this is already a smaller form factor build. And either of those cases will work as well!

      Hey there – stock on everything has been wonky. Looking right now, you could try GIGABYTE Radeon RX 5600 XT Gaming OC or PowerColor Radeon RX 5600 XT as alternatives, however there are priced a bit higher.

  6. Hi! I’m building my first PC and tried to copy buts of this guide. The following are parts I chose for my PC. I hope to spend around 600-900 max on it. I’d love to hear how I could fix/alter it! Big thanks 🙂

      Hi Jenny, what you have laid out looks good. I mean if it fits the budget you could fit an RX 5600 XT as your gpu or even a 3600x cpu. But other than that looks great, and I see you’ve increased to 16GB of memory which is fine too. Nice touch with the Bit Fenix Enso mech too.

  7. Hello! I want to build this PC but I am new to this so I have some doubts 🙁
    If I buy the ryzen 3600x and the rx 5600 xt, do I have to change the motherboard and power supply?
    sorry if my english is bad xd

    1. Post
      Author

      Hi JG – great question. If you switch just to the 3600X and the 5600 XT graphics card, you’ll be just fine as both the motherboard and power supply will still be compatible. However, I could caveat, that if you wanted to do some overclocking and get the 5600 XT, you might want to get a power supply that’s between 550W to 600W (such as the Thermaltake Smart 600 power supply if you wanted to upgrade the one included in the above build right now).

      Let me know if you have any further questions!

  8. Hello I was wondering if this build will be able to handle just modern triple a titles like Modern Warfare or Rainbow six? I’m new to PC been a console player my whole life but need a better change and do you feel like compared to building a PC at this budget worth it compared to buying the new generation of consoles coming out this holiday season?

    1. Post
      Author

      Hi Kevin, as for the question around being able to play Modern Warfare or Rainbow Six – yeah it would be able to no problem at 1080p and at high settings as well as many other games. And to be honest I can’t tell for sure as I haven’t seen much on the newer consoles, but PC builds are fun to do and are always very versatile as you can always upgrade them and swap hardware easily, and gaming online is free as there is no subscription as consoles have – and they second as an actual computer. I hope this helps.

      Hello again! This build will come with what’s needed. Thermal paste comes pre applied to the cpu and the rest will come with the cords needed.

  9. Would this game run rust really good? And also this would be my own first pc ever that I’m gonna build. So I wanna make it count.

  10. Hi would this be able to run Oculus Link (i.e. VR games)? It seems the specs are ok, especially if upgrading the memory to 16GB, but would it work nicely??

    1. Post
      Author

      Hi Roberto – if I’m being honest, yes it will work and be ok for some games, but I would try to stretch your budget and fit the highest performing graphics card possible into your budget for VR. So I would say you could opt for the alternative card above, the RX 5700, or even the RX 5700 XT (as included in the $1000 build) as these will give you a better range of performance. All in all though, you will be able to use VR, you just might not get the framerate you want in all games with the 1660 Super. Best of luck!

  11. Hello! I am wondering how this computer would run games like Arma 3, Dayz, and Squad compared to the 1000 build you have?

    1. Post
      Author

      Hi there JR, sorry for the delayed response – this build will honestly play those games just fine. You may be better off with the 5600 XT though for your GPU. I’m assuming you’re also playing with a 1080p monitor. I look forward to hearing how it goes!

  12. Looking to build a PC to run games like Arma 3, Dayz, Squad, Pubg at high settings. Will this do (I would get the higher end graphics card to be safe). Or would it be safer to go for the 1000 version instead? Hope to hear back and hope all is well!

  13. Hey Corey. First time pc builder. Would something like this be able to handle a game like Hell let loose or GTA5 on high settings?

    Excited to build my first gaming pc since I’ve bought pre built in the past. I’m mostly a strategy gamer but I do occasionally play more taxing games.

    1. Post
      Author

      Hi Dave, this would play GTA V on high settings no problem, and you could probably get away even maxed out hovering around 60fps at 1080p and for Hell Let Loose, my guess would be slightly scaled back (high settings) and you’d be perfectly fine! What sort of strategy games? 🤓

      Best of luck building!

      1. Thanks Corey. I’m a huge fan of Europa Universalis 4. I’m trying to get into hearts of iron 4 but it’s not really doing it for me right now. I’m looking for a good ww2 era strategy game. I generally prefer grand strategy over RTS. I grew up on age of empires.

        I would love to see a realistic FPS like he’ll let lose but with an included single player campaign. Two kids makes it hard to dedicate two hours to a play session without a pause thrown in there haha.

        One quick question regarding this build, is there a specific monitor you recommend or is there anything I should pay particular attention to when choosing one?

        1. Post
          Author

          That’s awesome, I’m going to be honest I haven’t played Europa Universalis or Iron 4 — but am a fan of certain RTS’s, especially StarCraft and was into age of empires eons ago! And yeah kids do throw a wrench into gaming haha, only have the one myself so far.

          For this build, I would look at really any basic type monitor with 1080p resolution and 60hz specifications to the size that you like. Typically you can see these on sale, but if you wanted one specific recommendation it would look something like this – https://www.amazon.com/BenQ-proprietary-borderless-Brightness-GW2480/dp/B072XCZSSW/ref=sr_1_1?keywords=benq+1080p&qid=1585089770&sr=8-1&swrs=A68FBDE907C64D3FE5AF051EB0BC684D

          Hope this helps!
