P.S. don't get the model that holds 24 2.5" drives (unless they come with the trays)... The hard drive trays are hard as crap to find and they want at least ~$30.00 each. I made the mistake of buying 2 of these units for a great price, but they came without the trays. Now, I am looking @ ~ $1500.00 just in trays alone...

. Sheesh, that $400.00 purchase on ebay seemed like such a great deal too... lol
