The newest development - I started putting shelves in. Bottom in first. I bought some scrap 1" aluminum T and 0.080" plate from the metal supply warehouse. I haven't put full kegs on yet, but it feels extremely sturdy. I can post some photos this weekend.
Unfortunately, the morning after turning it all back on, the freezer evaporator fan sounded like it bit the dust. It revs up, then stops. Thankfully it seems the compressor is working fine (it does get cold, just no blowing air around inside while it's on).
On the fridge side, both of my computer fans are almost toast (again). I bought the AC fans from Fry's electronics (there's only one option). After about a year, it seems the bearings lose lubrication and they make this horrible whining sound. Possibly it's just too cold or humid for them. My project this weekend is going to involve adding an AC outlet so I can plug this 12V molex ac adapter in and hook it up to new fans.
Molex AC Adapter
Fan 1, Silenx - has a 3yr warranty (at this rate... why not?). If it dies prematurely, maybe I'll actually get a free replacement.
Fan 2 is an Antec (I think) - it's the cheap option.
While I hate the idea of having to use AC adapters, I think it's clear that these Link Depot AC fans aren't going to cut it. Seriously - stay away. I also saw the CoolTron, but it looks suspiciously similar to the Link Depot fan. I'll pass.
As long as either the Silenx or Antec fans last longer than a year, I'm already break-even for a cheaper replacement fee. If anyone has any other suggestions, I'm all ears.
