Is this a CSE-847 knock-off? I've been watching for a good price on an 847 for a bit now.

yep same concept, also available from other manufacturers

I'd say price is okay, given that it has expander backplanes

Things to consider:
- Is it possible to source rails?
- Is it possible to source replacement PSUs?
- Is it possible to source replacement backplanes?

(at leat in germany/eu) the answer is closer to "no" ._.

Google points to 1 (one) shop for the rails (exluding ebay), same for the psu (there is a pn for a psu "housing" and a pn for psu "modules").

I believe that sander computer systems has AIC listed... If you need something, I can look it up with my account

I recently picked up a stack of cse847 with specs (x10/64-128gb ddr4/sas3+10g cards) for less than these, but im still tempted to offer on these.

There is something about getting a full original set of trays+trails.

Anyone which SKU version this is?
  • SKUA: 1 x 24-port SAS3 expander backplane + 1 x 12-port SAS3 expander backplane
  • SKUB: 1 x 24-port SAS3 expander backplane + 2 x 4-port SAS3 / PCIe Gen4 NVMe tri-mode backplane + 1 x 4-port SAS3 backplane
  • SKUC: 1 x 24-port SAS4 expander backplane + 1 x 12-port SAS4 expander backplane
Based on this data sheet I'm looking for SKUB version: https://www.aicipc.com/image/images/esg/rsc/RSC-4BT_Datasheet.pdf

SKUB for $500 would have sold out if our group here saw that.

I think the fan layout on here (3 on top for the MB, 3 on bottom for the lower drives) actually makes more sense than an 847. You could control the speed of the top fans based on CPU temps, and the bottom fans based on drive temps. I think that for $500 new, it's a good value as long as you can source rails and accessories.

The only thing about these compact 4u's that make a little iffy for me is the weight- 90 lbs just for the case+ps+rails.. yikes.

If it's a lifting/installation issue, a useful trick is to take out the motherboard tray and power supplies, then put them back in once it's racked.

I'm tempted to grab one but I'm not 100% yet. My MD1200 (2u, 12 slots) empty is around 20 lbs. Supermicro cases are around 15lbs (2u, 12 slots) A loaded 36x3.5 can easily hit 150lbs. Not a big deal, but it can be a hassle sometimes.

Note: According to the eBay post it comes with rails

Parts Included:
1 x RSC-4BT
2 x R1CA2122A - Power Supply
38 x HDD Caddies
1 x BP-HD4E02-TY - Back Plane
1 x H5521T100002 - Rail Kit
1 x Accessory Kit

I would assume there are 2 different backplanes (like in the CSE-847)... the one listed is probably for the front. as the rear is harder to get to...

I live in Austin (seller is in Round Rock) and pulled the trigger on this after an offer of $400 and I pick up. I was mostly content with my CSE-826 waiting on a deal to get rails for <$80 and thought I'd add an EMC disk shelf someday... well, this is a better deal then $80 disk shelf and $150 JBOD after what I assume I can sell CSE-826 for.

As an aside, I discovered that ThinkMate uses this exact chassis for their STX-TN XE36-24S3

Notes after unpacking this morning:
  1. There's a small bracket at the bottom of the case behind the fans that holds 2x 2.5" SSDs or 1x 3.5" HDD. I'll be sticking a hot 2.5" NVMe driver here and expect it to stay cool.
  2. There appears to be two UART cables (and includes a headphone jack to DB9 (I assume RS-232 but haven't checked) mounted to the bottom most PCIE expansion. Anyone know if there's a standard way to use this? Unclear if there's a MCU on these backplanes or if it's for firmware update?
  3. The drive caddies support 2.5" and 3.5" in one. No need for adapters which is nice compared to my Supermicro caddies.

I haven't powered it up yet to checkout the SAS backplane expanders, but I assume they are SAS3.

I grabbed one as well for $400. Will report back when I migrate my 2xMD1200's over.

Seller just countered a $400 offer with $450. :confused:

And just refused my $395 counter counter. ;)
