I use ATX utower cases with ATX PSUs and 120mm exhaust fans. There are only
3 that I know of: Evercase E3505B, which I have, Silverstone TJ08-B ($99,
no PSU), and Athenatech A301BS.400 ($44 with PSU). That's right, $44 with
PSU, $99 without. What makes it strange is that the latter two are almost
exactly the *same case*!
Here are Newegg pics
of the Athenatech A301BS case + PSU.
And here are Newegg pics
of the Silverstone TJ08 case.
The Athena does need a better exhaust vent, which can be fixed with a Dremel tool. Or if you have deep pockets, just buy the TJ08, which has an excellent exhaust vent.
I spotted something: it seems both cases are very well suited to DIY HDD suspension. Being a cheapskate with a Dremel, I bought an A301 and stripped it down. It's even better than I thought: both
sides of the suspension area are wide open (unlike my Evercase E3505s). Here's a pic:
Shown is the second version of my "SUV HDD suspension", with 2 HDDs and an internal 100mm spot cooling fan. You can read about the original here
However, the A301/TJ08 case is well suited to HDD suspensions of all types. In fact, I'm waiting for some parts from McMaster so I can create the lightest, skinniest, full suspension ever
to complement my "SUV Sus" (tm)!
