Sufficient Spec for Sky Go on Windows PC

I'm looking at buying a small form factor PC to run Sky Go on and HDMI it into a TV.

I've checked the min requirements

CPU

2.1 GHz Dual Core or Core2 Duo for Intel processors and 2.9 GHz for AMD.

RAM

Minimum of 2 GB.

Graphics

Direct X compatible video card with at least 1GB DDR 2 RAM, 600MHz GPU clock rate and 5 M pixel-per-second fillrate.

Sound

Direct X compatible sound.

Would anyone be knowledgeable enough to know if any of these would run it ok for me please?

One

Two

Three

Four

Or, if not, does anyone know of anything for a couple of hundred quid that might do the job?

Many thanks
