Mini ITX powerful gaming rig?

I'm preparing to build my new gaming desktop. I'm selling my extremely expensive gaming laptop to build this. I wanted to build a computer that is as small as possible so that I could still bring my desktop to a friends house and back again without lugging around a full ATX desktop. However I don't want to sacrifice power, I was just wondering if this setup will perform on a Mini-ITX board as good as it would on a ATX board?

CPU: Intel core i7 3770K
GPU: AMD Radeon HD 7970 OC 3GB
PSU: Cooler Master GX - 750w
RAM: Samsung Electronics Extreme Low Voltage UDIMM 8GB
SSD: SanDisk Extreme SSD 240 GB SATA 6.0GB/s

  1. Yes, that will perform just as good on an ITX board. But in a tiny case, you will be fighting heat constantly. The card and CPU will be much hotter than in a conventional case with good air flow. What Mini ITX case did you have in mind?

    You may want to consider a slightly larger rig, maybe move up to a mATX board and a case like this one:
    Still small and transportable, but much better air flow.
  2. Don't get that PSU. CM GX aren't reliable units. You'll do fine with something like SeaSonic S12II 520 or the slightly higher power, better voltage regulation and more efficient SeaSonic G Series SSR-550RM
  3. All depends on the size of your Mini ITX case
    I'm a huge fan of the Bitfenix Prodigy, small case with lots of room
    I have a i5 in mine with a CM Hyper 212+ heatsink as well as a HD5970 (one of the largest and power hungry cards made)
    No heating problems at all
    easy and portable
  4. I was looking at the Cooler Master Elite 120 Advanced - Mini-ITX Computer Case with USB 3.0 Ports and Long Video Card Support. I will start looking at micro ATX cases and mobos though. Thanks for the suggestions.

    Product Features:

    - Unprecedented airflow for a Mini-ITX case
    - 1/3 the size of a standard case
    - Supports standard length ATX power supplies with an innovative rear mounting system
    - Supports ultra high-end video cards (HD 7990/GTX 690)
    - Stylish aluminum front panel
    - Features a full size 5.25-Inch drive bay
    - Supports up to three 3.5-Inch /four 2.5-Inch HDDs/SSDs (converted from two 3.5-Inch HDD bays)
    - USB 3.0 Super Speed support
  5. The CM 120 is a nice inexpensive case for building a miniITX gamer. But it needs more ventilation. I built a gamer awhile back with that case and had to add another 120mm fan on the drive cage to keep the stock A10-5800K within specs gaming. There is only about 4" or so for a heat sync/fan.

    As you can see, I finally had to swap the stock cooler for the beefier Phenom II X4 cooler w/heat pipes to keep temps down. By the time I installed the HD 7850 2GB card, it was quite toasty in there.
  6. Get the CM 130 elite. It's about the same as the 120 but the front of the case has excellent cooling. and the disks are placed differently. I believe it will work excellently. However you may want to consider pointing the PSU downwards so it sucks air out and vents outside. Supporting the full size ATX PSUs you won't be able to SLI (unless dual GPU card)
