Yeah, right. msa50 won't be as much efficient as enclosure with 3.5 disks. 
There are MSA with 3.5, but they are even less suitable for home and not so cheap.

Ok, lets run the numbers for icybox
http://www.raidsonic.de/data/datasheet/raidon/EN/datasheet_iS2880_e.pdf
I'll probably need this model, iS2880-8S-U5D - 245$ on amazon.
And probably some kind of power supply required or its supposed to work form psu of the server? 60$
What about cables and adapter? Something like this probably, with 3-4 ports for expansion farther. 100$, easy to find cheaper I think.

Total ~300 + 8x2TBx80$ = ~1000 for 16TB of raw space. 
Are the numbers correct?
