Minimum Recommended with GTX 560 Ti is 500W, 550W is enough even with the HDD. HDDs pull between 15 to 30 watts while your GTX card hoards 170W; with the rest of your components you should be in a safe power zone.
My questions are:
Is there any technical problems with the config?
Is there a better itx-case? maybe Silverstone SUGO GS07
Are there better options for cpu-cooling with the config in the Q08 case?
For Info, then I'm skimping abit on parts than are easy to improve, so next payday/bonusday I will buy a HDD as backup for the SSD, and in time a better GPU.
I watched the video and built a similar system as a gaming box for daily use, and to take to LAN parties every couple of months.
I swaped a few parts in and out but this is my final configuration:-
“Red Cube” PC – Mini-ITX Gaming Rig
• Lian Li PC-Q08R Case
• Zotac Z68-A-E Wifi ITX motherboard
• Intel i5-2500K CPU
• MSI GTX 570 Twin Frozer III
• 8 Gigs of Corsair 1600 Meg DDR3 RAM
• Corsair 120GB Force 3 GT SSD SATA III
• 2 Tb WD Hard Drive SATA III
• Corsair H60 Water Cooler with Noctua NF-P12 High pressure fan
• Thermaltake 700 Watt ATX Power Supply
• Samsung Blu-Ray Combo Drive
• BitFenix Spectre Pro 140mm Black Tinted Red LED Fan
• Windows 7 Professional 64-bit
Be careful of which power supply you choose. Unless the case the youtube guy had was somehow different from mine, the AX750 wouldn't be able to fit. There is only 160mm gap between the back of the case and the drive cages. All cable managed power supplies need additional space as they have a pile of connectors at the end facing the drive cage.
You need to find a shorter power supply that is 150mm (5.9") or even 140mm (5.5"). This will rule out most cable managed power supplies or probably any power supply with a 130 or 135mm fan.
The corsair hx-650 is 150mm deep and has flat modular cables that can be bent to fit the case. There are several others available too. Alternatively get a good quality non cable managed power supply with a 120mm fan. Most of these are 140mm deep and you can select a model with the right output cables to suit your build. Then there wont be a pile of unused cables to tie up out of the way.
Alternatively Lian Li make a bracket to allow you to shift to position of the power supply further back. Personally id prefer no to do this as it making a small case have a larger footprint, which is not what the idea of ITX computing is all about.
I used the stockcooler, which works out nice, as long as I don't overclock. It is pretty quite until the speed step kicks in, and the silverstone fan speeds up and down.... I'm going to turn speed step off in my bias. I don't think it will change much in regards to cooling.
