for the price, the antec 302 is a good call
the zalman z3 plus is a good case too, the stand out bang-for-buck case out of those listed
the nzxt source 210 is a decent alternative to the z3, if you don't want the bling and if you want to watercool your cpu with a 240mm rad (the z3 can't support this without modding)
the neos is half decent, but it only comes with one case fan, so it really isn't that bang-for-buck case that it's made out to be (once you factor adding another 4-5 quid for the 2nd fan)
the corsair 200r is cheaply made, though not reflected in the price. ie paying for the badge.
imo, i'd go for either the 302 or the z3. but as always, cases are a personal choice. so go with the one you like best
