For pulling cables, I highly, highly recommend flexible conduit (smurf tube), and then pulling the cables through that (with a fish tape). Much easier than dealing with snags and kinks in the cables while running them from place to place.<br><br>-Aaron<br><div class="gmail_quote"><div dir="ltr">On Sat, Feb 4, 2017 at 15:12 Jonathan Morton <<a href="mailto:chromatix99@gmail.com">chromatix99@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br class="gmail_msg">

This shouldn’t be too difficult or expensive.<br class="gmail_msg">

Consider this AM1 Mini-ITX build as a baseline:<br class="gmail_msg">

The long PCIe slot is electrically x4 v2, but will accept any size card. There’s a Mini-PCIe slot for wifi, and built-in GigE. The CPU is weak but efficient, and genuinely quad-core, giving you the option of dedicating cores as you describe. The whole shebang can be powered with a laptop brick instead of a conventional PSU. Best of all, AMD graphics are the least troublesome out-of-the-box with Linux.<br class="gmail_msg">

Even cheaper and quieter, but might not be stocked any more:<br class="gmail_msg">

If you insist on a true x8 slot, then we need to move up a step:<br class="gmail_msg">

Here the first long PCIe slot is x16 v3, as good as you can get. The second one is x4 v2, but is disabled if you use the M.2 slot. Ether way, there is a spare x1 slot and an old-skool PCI slot besides. The CPU is faster than the AM1 build, but is much less efficient. It’s quad-core, but uses CMT, so the cores are not totally independent; I don’t know how much that matters for you.<br class="gmail_msg">

If you prefer Intel, this is an inexpensive build:<br class="gmail_msg">

However, this is a 2C/4T CPU rather than a true quad-core. Again, that might or might not matter in practice.<br class="gmail_msg">
