Best Mini PC for Dolphin?

[sublime]

I have been looking to buy a mini pc for my living room. I want to play wii and gamecube games with my girlfriend kids.
I will use linux of the OS.
I like the mac mini but i'm sure i can find better options.

What do you think of these:
ASRock VisionX 321B
Intel Ivy Bridge Core i5 3210M (2.5 GHz / 3.1 GHz Turbo Mode / 3MB cache)
AMD Radeon HD 7850M

Asus VivoPC VM60
3rd Gen. Intel Core i5-3217U Dual-Core 1.80GHz Processor
4GB (16GB Max) DDR3 SDRAM SO DIMM 204-pin Memory

Dell OptiPlex 3020
Intel Core i3-4150T 3.00GHz
4GB of DDR3

GIGABYTE BRIX GB-BXI7-4500 or i5?
Intel Core i7 1.8GHz
Intel HD Graphics with HDMI


English is my second langage, sorry for my mistakes.
Thank you!

At the very least I would get this http://www.newegg.com/Product/Product.aspx?Item=N82E16856164012 Gigabyte Brix with the I7-4770R
or the http://www.newegg.com/Product/Product.aspx?Item=N82E16856164011 Gigabyte Brix with the i5-4570R
The best would graphics would be this brix http://www.newegg.com/Product/Product.aspx?Item=N82E16856164020 as it has an i7-4710HQ and a GTX 760, but the CPU is slightly slower than the other i7

The brix with the desktop 760 has known thermal throttling issues I believe, just letting you know. Also, do you think you could fit a mini itx case?

Thanks for letting me know, I had a hunch that might be an issue.

Fit a mini itx case what?

I will not experience any lag with the Gigabyte Brix with the i5-4570R?
This one have thermal throttling issues too?

[KHg8m3r]

I have not heard of thermal issues with the Brix with the i5-4570R, and we have recommended it to people before here on the forums and no one has come back to complain about it. The only thing that we also recommend is to replace the thermal paste in it with some better paste, like Arctic Silver, to be on the safe side.
