Koolance should make the Aquabay M4...

[JuanPabloCuervo]

dont know why Thermaltake has great products and discontinues them...

i love my 4x Aquabays, the only flaw in thermaltake was the low quality aluminium screws that break so easy.

I was not a fan of the Aqua bay. Forcing you to use a 5.25in drive bay to cool a drive is silly. If you look at the Koolance specific HDD coolers they avoided that issue and still allow you to leverage the 3.5in bays and liquid cool the drive.
