Making NAS
kitamesume:
there are some not too expensive SLI LGA775 motherboards, instead of filling them with GPUs just fill them up with PCIe Sata cards. good option imho.
[90$] EVGA 113-YW-E115-RX LGA 775 NVIDIA nForce 730i HDMI ATX - 8SATAII 3.0Gb/s with Raid support.
[120$] ASUS P5N-D LGA 775 NVIDIA nForce 750i SLI ATX - 2xPCIe-16, 4SATAII 3.0Gb/s with Raid support.
2nd hand sets are waaay more cheaper :D

how do you search PCIe x4, or above, sata cards on newegg? i could only find PCIe x1 cards.

On using older equipment, I would recommend to not use a system boards based on PCI. What I am running into is that PCI SATA cards are having problems with the larger drive and you will spend time moving the PCI cards around trying to make things happy. Certain combinations of PCI SATA result in POST freezes and improper drive detection. Could be my crappy hardware. Most any PCI card will need to have their flash undated for use with drives over 1.5TB, a lot of them been sitting on the selves for a few years now because of low demand for them.
I am going to look for a i3 system to replace it; Been seeing prices for MB's for about $50 on sale and processors at about the same.

Honestly, I don't know. I based my statements on memory (which, quite possibly is not accurate). What I understand is that the throughput speeds of the x4 PCIe slots are able to use all of the potential data transfer rates that modern SATA drives are capable of. The x1 slots can bottleneck the speed ... which might not be noticeable on a single drive, but in a performance RAID could be an issue.
Now that you've made me think on it more carefully, I think I've got that "info"/"impression" from the SSD-on-a-PCIe card solution, such as:
- http://www.newegg.com/Product/Product.aspx?Item=N82E16820227521
These are basically SSD chips arranged in a RAID on a PCIe card ... and it is usually recommended that they be placed into x4 or x8 slots.
So, for a more normal NAS solution ... maybe the x1 slots are adequate. I don't have time to research it just now and attack my doubts.

hoh, yea, though those SSD over PCIe are insanely expensive ;D
well, now a days its easy to find a 2nd hand LGA775 for under 200$ so thats one option to get.
i3+decent mobo with lots of PCIe slots will be a plus too. specially the i3-2100T, good low power processor.
does atom rig and/or AMD E350 rig have enough slots to host a ton of HDDs? i get the fact that its the most adequate setup but using only USB for HDD isn't really that good either.
for the case, pretty much anything would work, but the HDD will be housed outside, AKA hard drive rack. its pretty easy to build an aluminum box with holes in it, plus you could cut out some bigger holes to put some fans on it.
note: the width of the external box should be a fit for the HDD's width, each HDDs should have a spacing of half an inch or more when stacking upwards, you can build the box as high as you want, cut out slots at the front and place in fans too if you want.

though this uses angular bars.
now this is funny.

Anything lower than x4 will cause bottlenecks for the gigabit ethernet. So while a x4 might bottleneck the data transfer from harddrives, It's more than enough for network transfers which is the mainpoint of a NAS anyways.
