Yes, there is not much room for the PSU I have another thread I am going to start with a PSU install guide but it is very tight in there and that one bolt is impossible to put back in without magic fingers.

OK NEW PROBLEM:

Avalon firmware v. 3.21 stops hashing but thinks the miner is still alive. Can still log into tp-link.
Hard reboot with power cycle gets it going again. This happened to two of my miners last night had to hard reboot them in the morning. Soft restart of cgminer also works.

so basically this problem already discussed here: https://bitcointalk.org/index.php?topic=159827.0

this is a known issue in 0321&0325 firmware.
xiangfu made some beta version, please try them.

and we are finding the root cause, will take some time.

As a temporary solution until next stable firmware update, does anyone have a monitoring script that periodically checks the hashrate and restarts cgminer when it dips below certain threshold?

yes, here:

also, some ppl are having success with 0325. i'd try that.
