Question about power supply and cases (and general build review)

[thebiscuit]

I'm looking to build a new PC for gaming, i'm going for decent performance on current games, but i'm not after ridiculous resolutions and framerates. My budget is about £350 to £400 ish. This is what i've come up with so far:

I have a perfectly servicable DVD R/RW and a 200 gig IDE drive in my current computer that I intend to use, as well as keyboard/mouse/monitor etc.

My question is on power supply and cases, I don't want to waste a huge amount on a case, i'm not intending on overclocking so it won't need a huge amount of cooling. I also have no idea what i'm going to need power supply wise, I have plenty of cases and a 400w psu at home, so will that do or would you recommend getting a brand new one, and which?

Also if theres anything horribly wrong with the rest of the build pointing it out would be nice.

For the spec if your gaming I wouldn't get a 8600GT it is a poor card. A ati 1950xt will be better.

That 8600GT won't give you decent performance by today's standards, it would be better to go a bit further and get an ATi 38xx based card.
The 512mb versions of the 8600 cards are crippled by the 128bit bus.

What brand is the 400w? Make sure it's decent and not a Q-Tec or unbranded.
OcUK's own Huntkey supplies look ok, not heard any complaints.

The Akasa Zen is under £30 and looks quite suitable.
