My friend and i were hunting around for suitable cases for this exact same scenario and came across this case from Silverstone. http://www.silverstonetek.com/products/p_contents.php?pno=sg03
In real terms to give you a rough idea of the size, the case is not much taller than his Creative 5.1 subwoofer and narrower! I was somewhat impressed, i even considered changing my Antec 900 for it, but then i'd miss the air-con for my room!
Silverstone actually recommend suitable PSU's on the website, however most standard 150 x 160 x 85mm ATX PSU's will fit. I would recommend one with short power leads, perhaps modular too as cable management within this case can be a little tricky.
The Apevia X-Qpack2 can fit those things, but I cannot recommend it because of quality issues (and of course you wouldn't use its included PSU). It's a wonderful design, but poorly executed. I mention it only because you may want to look at its layout for comparison.
For any micro-ATX case, a modular PSU is a very good idea. The X-QPACK2 design can take a full-sized one; I used a Mushkin modular which is actually a little deeper than standard but still fit.
20 quid, as usual problem always finding a case that will support a full sized atx psu because lets face it micro atx psu's are just lame and don't provide the 650w + juice you need for the modern set up.
measure it all up and you have a cheap NORMAL looking case as oppose to these hideous cube things with see thru plastic on the sides, that case I suggested can even house a 120mm fan which is a must for cooling and I'll even reccomend a fan to put there:
