Just an update.
Everything has arrived bar the graphics card.
P50 case:
OK case. A bit on the light side but as long as you don't drop kick it down the stairs I'm sure it'll be fine. Not too bad to work with but.... My Holy Grail of builds is the small form factor system under water.
Trying something different this time using AIO coolers (240 and 120) and given that this case is "supposed" to support 2x 240 rads (one in front, one in top) I thought it ideal. Well, maybe it would if you removed the optical drive bay, but with it in there you cannot fit a 240 in the front (snug fit for 2x120 fans... no chance the extra length of a rad will fit).
A similar story up top. A rad fits this time, but.... with the optical drive installed you can't fit both fans to the radiator, and I'm a little concerned with the tubing as the HDD cage doesn't leave much room and since it's riveted in, I can't remove it easily. Going to have to try to get some anti-crink on there.
Sound proofing is non-existent. Going to have to fit some, especially since I'm gonna need to develop positive pressure in the case with only 1 fan on that 240 rad.
All in all.... OK case, but almost sent it back as I want the optical drive installed.
CPU: enough said.
H100i: easy install (can't blame Corsair for the case issues), bit noisy at boot up. Only issue is that the Corsair link cable uses up an entire USB header, even though it only needs one USB.
HX750i: Again, easy install, but even though the Corsair link cable is now just for a single USB (i.e. the half header variety), there are no spare headers left. Whilst the H100i has a USB port on it, I can't find any supplied cable to daisy chain the H100i to the HX750i. Shame that.
MoBo: Still getting used to UEFI (slap BIOS after that if you want too... not going to get into that arguament). Needed the F5 BIOS for it to recognise the SM951, but once upgraded it was simples.
SM951: Not had a chance to test the actual speed, but now that Win8.1 Pro is installed, it feels like it takes as long to POST as it does to land me on Desktop.
Still to do: Configure ISRT and bring up the HDD+Cache sub system. Install graphics card (eta end of the month). Tidy up the cabling... bit of a mess atm. Soundproofing.
Off to Heathrow at 5AM so no more tinkering time until next weekend.
