Just build yourself a wooden GPU frame like this

And buy 2 more risers and you won't have any heat issues.
Also you can undervolt those 280X.
Sad to see you leave ETH mining.

4 MSI 280X GPU cards
Asrock 970A-G/3.1 motherboard AM3+/AM3, supports up to 220W CPU and a total of four GPUs
8gb Ballistix memory stick (1)
240 gb Crucial ssd
2 USB powered risers 1X to 16X PCIe
DVD reader, writer (optional, remove $10 if you don't want it)
Choice of processors: Sempron 145 (OK if just mine) or FX4350 (better if you want to run a geth node for running solo or just supporting the network)
Linux 14.0.4 preloaded on ssd; geth is current (synchronized), ethminer and qtminer installed
Basically, just replace my wallet id in qtminer string (provided as a text file on desktop) with yours, connect to internet with ethernet cable, and you will be running in no time
Four 280X cards require at least 1000W PSU (I use my favorite EVGA 1300, but you can use something else).
If you absolutely need it, I can add that EVGA (used for a month or two) for extra $140, shipped to US, but prefer to keep it for now.
Total production of ethereum at least 80-81 Mh/s as is (without optimization); you could probably get up to 84-88mh/s from it with optimization, but I don't guarantee it.
Currently 81 mh/s produces ~$490/mo

Price (without PSU):
$1020 +shipping (with Sempron 145)
$1090 +shipping (with FX4350)
Will ship to US or Canada from 77025
I will NOT ship to EU or anywhere else because of too much hassle
Payment in either btc or eth according to price at the moment of the deal.
The deal is take it or leave it; I already put in a fair price for everything and can simply continue to mine at $490/mo.
cause for selling: it is in my office and in order for cards to be cool (73C), i have to run fans at 90%, which makes a humming noise at ~59-60dB, which is distracting in the office, but totally OK elsewhere.
