Thanks for all the other replys @JaredKaragen and @vapourminer, about the risers I knew it but forgot to mention at the post I made. I've got a seller for that, there's no problem

Also I got some old HDD that I could use to mount. So I think I won't be buying any SSD, unless you tell me that does affect or somehow improves performance on mining.
ssd vs hd. no performance difference unless you rig reboots a lot, as longer boot time costs mining time. but its pretty insignificant and a well setup rig wont reboot except for external events like power sag/glitches.
main reason for ssds is when you set the rig up and tweak it, waiting for slow hds is maddening to me. driver reloads, os updates, miner restarts, all take more time and time is the one thing i value over most other things.
16 or 32 gb ssds are cheap and will allow windows, *nix and dual boot with room to spare. some OSs can use usb sticks also, smOS for example.
used hds in the past as i has plenty of them but all my rigs, miners or otherwise, now have ssds for os drive.
as for "t" series intel cpus, they are low power variants. saves on power costs. i have a 6400t in my htpc that i will probably move to my basement rig, which currently has a g1840. then ill toss a 6700t in the htpc. worth it if your power costs are a big concern.
