Sparkle

--- Well ... maybe they are better now. I don't think I've used that "stretched" model.
If I needed to replace another unit that size I'd spend try to spend the little extra on a Enermax or Fortron. But, I'm really sick of the lack of options for that form factor PS. Even if you get a reliable unit ... these small units get very hot. My brother had an almost identical mATX Clear case as the ones linked above ... Let's just say that combining:
The extra heat of a SFX power supply +
Acrylic's ability to insulate (keep that heat in) +
Less space for airflow +
Smaller Noisy Fans
------------------------------
= Overheating waiting to happen.
My brother later switched out to a spare tower case and Power supply I had laying around... and went "Office Space" on the acrylic case.
If you really want something transparent ... you might want to try one of these and let us all know what you think

They handle full size ATX power supplies. I haven't had a chance to get my hands on one yet though so this isn't a hands on recommendation ...
Clear - $140

UV Transparent Blue - $150

True it can handle Full ATX, but the foot print is more like a large UltraFly/X-QPack. If you want to view components the layout is great! I've not seen a better idea for a "Clear" case.
The other option I try to give people looking for "Clear" is the workbench style open air "cases". True this isn't exactly LAN friendly ... but it's nice to have none the less.
Standard Size "Black" - $80
